What’s your opinion on sharing your presentation slides (online for anyone to access) after speaking at an event where eventgoers paid to hear you (and others) speak?

I think sharing slides is almost always the best thing for everyone:

How long does it usually take you to prepare a presentation?

Damian Conway (one of the best technical presenters I’ve ever seen, who also runs amazing tutorials on giving great talks) says “to produce really top-class presentations, budget at least ten to twenty hours per hour of speaking”.

What are some tips for a successful Ignite talk?

Practice. All public speaking can be improved by repetitive practice, but this is especially important for ignite talks. The one-slide-every-15-seconds format is extremely unforgiving—if you haven’t nailed it, in private, speaking out loud at a sensible pace there’s no chance you’ll be able to keep up with the slides when you are on stage.

I have embedded videos in a PowerPoint presentation (using a fix), but now they do not play when I save the file as a .pdf. Any idea how to make this work?

It isn’t possible to embed a video in a PDF file. If you want the embedded video to play you will need to distribute the presentation in the original PowerPoint format.

Presentations, when’s the best time to give your personal background?

It’s rarely a good idea to include this—usually it adds nothing to the audience’s understanding of presentation, unless you are speaking on a topic that really needs that additional authority (security presentations sometimes benefit from this)—in which case keep it to a couple of sentences, don’t share your entire professional history.

Does preparing before a presentation actually help one’s presentation?

If I write a blog, then use the same information to create a slideshare presentation, will that help or hurt my website’s SEO?

I would be absolutely amazed if you were hit by a duplicate content penalty for this. To a search engine spider (even a super advanced one) content formatted as a blog post and similar content repurposed as slides will look completely different.

How do some public speakers memorize so many statistics when speaking on stage?

It’s really not hard. If you’re memorising a complete speech, remembering a few statistics is easy in comparison. Also, the stats you use in a speech should be meaningful (otherwise thy include them at all?) which means the have a built in mnemonic.

What are the simple ways  to gain more self confidence in public speaking?

Be confident that you understand your subject matter. Practice, out loud, in private, as many times as possible. Have notes in your pocket so you know you can fall back on them if you really need to (you probably won’t, but I find knowing they are there helps with nerves). Then get as much speaking experience as you can. BarCamps / Unconferences are a useful place to get started.

Does anyone ever had the experience where they could carry on a conversation with someone very well, but stutter and go blank when public speaking (eg. informal introduction) in front of a crowd?

This is extremely common, and will certainly go away with experience... but being well prepared is never a bad idea with respect to public speaking! Even for informal introductions it’s worth figuring out what you’ll say, writing it down, rehearsing it out loud several times in private and memorising it.

Public Speaking: Where can I find someone to represent me as a speaker?

There are speaker agencies that specialise in this kind of thing, but they’re mainly targeted at larger events which expect to pay $5,000-$50,000 or even higher for speaker. They might not be as well suited to setting you up with gigs at startup events, which are less likely to pay enough money to make it worthwhile for an agent (most agents take a cut of the speaker fee).

What are some creative programs to use for presentations?

Here’s a trick I’ve used with success in the past: set up your Mac to have 9 virtual desktops, then arrange your “slides” on each desktop using a combination of applications. I’ve done this with a title slide in keynote on the first desktop, a text editor with some sample code on the second, a terminal prompt set up for live coding on the third, a browser showing a demo on the fourth and so on. Learn the keyboard commands to switch between desktops and off you go.

Events (leisure): How can I get into presentations, mixers and meetups without paying the entry fee?

Speak to the organisers and volunteer to help out at the event. This works for all different sizes of events and is a very effective way of getting in to an event for free. As a volunteer you also get a great excuse to interact more with the attendees and speakers.

Product Demonstrations: What’s the best way to view/demo a website offline at an event?

If this is a static website (just HTML, images, CSS and a bit of JavaScript) you might be able to get it running on your laptop using a web server. OS X prior to Mountain Lion had a built in Apache which could be turned on using the “Web Sharing” option in the Sharing preference page, but it looks like they’ve now removed that option—a way of turning it back on again is described here:

Why are TED talks 18 minutes long (or less)?

I imagine it’s because enforcing a shorter talk time results in consistently higher quality presentations, by forcing speakers to carefully structure their talk and strip out any unnecessary details.

Does Google (company) have their own Audio Visual department for their large conferences, or do they contract another company?

I believe it’s their own in-house team—when we ran the first DjangoCon at Google’s Mountain View HQ a few years ago I understood that the video team were their own (the same team that records their internal Google Tech Talks). It might be an external company that they contract in, but it felt like they were permanent staff.

Public Speaking: Where is a good place to get started as a speaker?

Start small. There are plenty of small local events around that accept (and even encourage) first-time speakers. The single most valuable thing you can do to improve as a speaker is to get as much experience as possible.
