Show HN – Presentation.io: Broadcast presentations live across devices

First, I would suggest adding a demo video on the front page. If you like your page to have as little content as possible - that's fine, but unless you add something small that tells a lot (like a video), I suggest many people will just give up very early on.

Second, the "used by" section. I think that if you manage to get testimonials from individuals, it will look better and feel more personal.

"SYNCED PRESENTATIONS TO ALL DEVICES" - I don't get why this is formatted this way? I'd put it in the center with another smaller sentence underneath that briefly summarises the product.

I think what you offer is pretty neat (if I have managed to understand it correctly) but I feel you should do a bit more work re: selling it better.

Can I assume based on your design that you will handle that?

Don't want to be snarky, but guys... may be you add smth else to design? Like what you can and can not do...

The above was feedback, btw I like the design :-)

Also, the first thing I thought after clicking is "I wonder if they should get the presentat.io domain name"

If it was a/v I would be very interested.

Otherwise, we rolled our own slide-changing tool called Motif. Basically we export our slides to images (PNG), upload them to our server, run a script to generate thumbnails, and send students attending our JS workshops to the right URL. I get to see a gallery of slides and back/next -- and when I click to a slide, the update for all students is practically instantaneous. It works on any device with a web browser capable of Ajax. Yay Ajax polling.

We syndicate a/v with Flash, using Influxis. So that video doesn't work on an iPad, but the slides do.
