I'm not sure if I like that LinkWithin that I just added to my blog. It looks pretty, the idea is good and I am going to keep the widget around for a while because it is providing me with amusement, but I can also see it driving me crazy as time goes on. The technology that finds similarities to other posts must still be in alpha stage.... or something.
ETA: or maybe it's genuinely random. At any rate, it seems to shift every time I reload the page.
