Readers here have probably come across the new service coComment, a means of tracking the comments you leave around various blogs.  The buzz on this one is huge.  What are people saying?

• Scalability.  The folks at coComment are getting slammed and though they say more servers are on the way, scalabilty is always an issue for Web 2.0 applications, isn't it?
• Greasemonkey.  If you're a Firefox and Greasemonkey user, the bookmarklet to track a comment can now be automated so you don't have to remember to click each time you post your thoughts online.  Brian Benzinger put one script together and got lots of discussion of his review of the system.
  
• Platforms.  The system works with most of the major blogging systems, but not all.  Movable Type was just added today.  Drupal is rumored to not work at all.
• Navel gazing.  The funny folks at MoBuzz.TV video blog seem to be of the belief that only an ego maniac with delusions of grandeur would be excited about this service.  If that's the case then the web is full of ego maniac's with delusions of grandeur.  Maybe we already knew that, but I'm not so sure they're right.  So who's got a story about something really useful coming from being able to track your comments or the comments of some one else?  Really, this is serious - or is it?
• The walled garden of conversation.  coComment currently tracks comments left in response to yours, but so far only those left by other coComment users.  Who cares what newbies have to say anyway?  No, to be fair I'm sure this is a technical matter - but it sure would be nice to see it overcome.
• Alternatives and Identity.  There's a nice conversation over at Bright Meadow on a Spanish alternative called MyCo and several ideas of how a system like this could be integrated into larger efforts around Identity and Attention data.  No mention of any of this yet over on the Attention Trust blog.

I personally will probably continue using this system.  I do think it is one of several small service features that ought to be included in an Attention/Identity suite offered by a benevolent organization like the Attention Trust.  It seems useful enough, basic enough and unlikely enough to ever be too interoperable with other systems that I'd worry about putting all my eggs in one new little basket.  I noticed that searches of the coComment company blog for XML and "export" came up with nothing...so I do worry about my info being locked in. You could say that better to be locked in to one vendor than to never have easy access to the info at all - but I think the web can do better than that.  I won't be posting a list of my comments elsewhere on my blog, unless I see something more useful than egotism resulting from other folks doing that.
