Web 2.0 startup companies

I found this list of new, Web 2.0 companies in a blog post by VC David Hornik entitled "Under The Radar: Why Web 2.0 Matters" Ever heard of them? Do they provide valuable services?

• BubbleShare

• Dogster

• Flock

• Goowy

• Kaboodle

• Loomia

• Meetro

• Riya

• Sphere

• TailRank

• Wink

• Writely

Does anybody have anything great to say about these companies, in terms of whether they seem like they'll be the next Google or Microsoft, or at least be moderately profitable?
