In my opinion. Facebook is the only one that really counts. Myspace is for kids these days. Twitter is for sports superstars and rock stars, and their teenage followers. I know nothing about Google Buzz, and don't personally know anyone that uses it. Just a few years ago, a lot of people I know were mostly on myspace, with a small percentage on FB. Over the last few years, they have all gravitated to FB. I suppose it all depends on the nature of your site.

What's really missing from Dolphin see more is a decent activity feed. The Spy and Wall modules are next to useless. It prompted me to buy the 'Spywall' mod, but I can't get it to work on my site. D7 is on the same path as D6. It's a cluster of half-baked modules, that will probably never get enhanced once a third party module come along to provide the missing functionality. We will all end up in the same place all the D6 users were. We'll all have a Frankensite, pieced together with third party modules from all different directions. Because of this, upgrading from D7 to D8 will be impossible. I'm convinced, that delivering robust functionality in their modules, is not part of their plan. Why should it be, when the very same coders can sell mods to provide the missing functionality. I guess I'm getting a little off-topic, so I'll shut up now.
