More features does not a better product make. More importantly, you can have 100x times Veotag's features, but it won't matter unless you can make people understand, instantly what your product is.
Now I imagine I'm a random stranger on the internet stumbling across your site. You really have less than 5 seconds of time before I click off back to YouTube or something. I just don't have that much attention.
The location of the diagrams on your website is the least of its problems - it is almost irrelevant. I would suggest first getting rid of about 90+% of the text on your frontpage.
Paul Graham's suggestion to take a look at wufoo.com is a great one. That's one of the best homepages you can find on the net. Simplify simplify simplify and reduce reduce reduce.
Thanks for continuing to engage!
1. Messaging.
I am confused about what Juwo really is as well. It seems to be a way to tag audio or video by time? There is way too much text on the page. I know Juwo probably has a ton of features, but you need to nail down your core message and drill it in (and design your product around it). Can you describe what Juwo is in 5 words or less? Now what about 2 words? Anything longer than that and you've exceeded my attention span.
2. Design
Horizontal scrolling plus web design circa 1995 plus religious proselytizing doesn't inspire confidence that this is something I want to use and would enjoy using. I strongly recommend looking at other websites featuring downloadable apps such as Skype.com or Trillian, etc to see how they are approaching this. This is compounded by the lack of a clear message as to what your product is.
From what I understood of the core idea, it seems useful, but I can't see myself downloading a standalone app for this functionality. Btw, Have you checked out http://www.veotag.com? Seems like a competitor.
