I've read in many places where Microsoft purchased Foldershare. I've looked at using Foldershare but my USB drive does the trick plus more if I want. So subscribing to foldershare really wasn't a good option for me. Today, Joel has heard (not sure where) that Microsoft will now make Foldershare free. That would be cool and I think I'll give it shot if that is the case.
I went to the site and I see the Microsoft logo in the footer but I don't see that the service is free yet. I'm not sure if Joel forgot to link to the article/post or he's just got the inside track.
Update: Joel found the link and provided it in the comments. Look at the last sentence.
