I think that the blog function is great, I think it offers a huge resource for people to share, comment and learn from our peers.  That said, I have a huge problem with the way this system is setup to "fire and forget"... 

The burden for someone to manage the threads they commented on and perhaps want to stay engaged with is a big pain in the ass.  I would have to save links and constantly check back to see if anyone else has commented on those.. etc.  Perhaps i'm missing some amazing solution that's already there, but i don't think so...

Solution...

In each of our profiles.. there should be a blog comment list.  Every blog I comment on should be added to a list i can quickly look at and revisit anytime from my own profile page (that, fortunately is easy to get too).  If you really wanted to go the extra mile, allow a person to "watch" a thread and have that be another list... because sometimes we all see blogs that are interesting, but perhaps we don't really have anything to add, but certainly value to comments being left... 

What do you think?
