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

Your website is not telling me what it does and how. It doesn't matter if you have a Pricing link.

I think I get the idea of the product, but with the information you have provided - I can never be 100% sure.<p>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.<p>Second, the "used by" section. I think that if you manage to get testimonials from individuals, it will look better and feel more personal.<p>"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.<p>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.

In my place we routinly use PowerPoint presentations 10-25MB with embedded Excel, images, videos.<p>Can I assume based on your design that you will handle that?<p>Don't want to be snarky, but guys... may be you add smth else to design? Like what you can and can not do...<p>The above was feedback, btw I like the design :-)

Nice design, good features to collaborate. But no option to delete uploaded presentations???

This needs something that shows how it works. I wouldn't sign up with no visuals.

it looks neat, but I wonder how it handles content flow / scaling on smaller screen sizes.<p>Also, the first thing I thought after clicking is "I wonder if they should get the <i>presentat.io</i> domain name"

Very cool! Nice design too.

As far as I can tell, all this does is sync slides, right? No a/v?<p>If it was a/v I would be very interested.<p>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.<p>We syndicate a/v with Flash, using Influxis. So that video doesn't work on an iPad, but the slides do.
