I was checking my referrers today (as I do from time to time—it's not as damaging to the brain as certain people's referrers lists) and discovered a visit from BlogShares with my blog's address on it. So I surfed on over and discovered that my blog has been listed on the service, and I wasn't even aware of it!
Well, I quickly registered to see if I could buy some stocks in my own weblog, but all the non-reserved stock had already been sold (besides, the current price was more than the new user's inital allotment of play money). Happily, the reserved stock is for the blog owner, so I "claimed" the blog (which you can see with the BlogShares graphic off to the left). Will I do anything with this? I don't know...but it's cool.
