Tumblr v5 Released

Can someone summarize the video for those of us without speakers and/or at work?

I already ranted about this on my tumblelog: I'm not at all a fan of this release. Ugly, cluttered design, new features that aren't entirely necessary, and a lot of wasted space. I joined Tumblr for its simplicity, for how every feature added something. Most of this stuff is redundant crap.<p>EDIT: the rant is at <a href="http://unalone.tumblr.com/post/70951166/is-it-just-me-or-is-tumblr-constantly-getting" rel="nofollow">http://unalone.tumblr.com/post/70951166/is-it-just-me-or-is-...</a>

Tumblr is a great example of a startup which follows the 'tribes' principle by Seth Godin. They came up with an idea, began with the product, and let the tribe dictate where it goes next.<p>It's expanded to much more than a overly simple blogging interface, now it's a full fledged blog app. V5 looks amazing and the video demo does it great justice.

The new features look great, but I'm surprised no one has discussed that screencast. That was the slickest and sexiest product demonstration I've ever seen; I watched the entire thing, and I dont even own a tumblog

Sexy video, and the fact that they mostly iterated on their previous features is probably a good choice.<p>This is going to be an interesting year for tumble &#38; microblogs, can't wait to see what's next :)

Do any start-ups here power their (startup) blog using Tumblr?<p>If so why did you choose Tumblr over creating your own; easier to create/maintain, better SEO, additional way to promote your work.... ?
