TL;DR it became a shopping site in the Philippines and then went belly-up. True story.
Multiply was sold to some entity overseas. Apparently the shopping had always been there, but we were never really noticed. It was huge in Asia. Anyway, in December 2012, they shut down the social networking part of the site, which seemed really dumb because it turns out that the stores actually used the blog part of the site for their goods and there was actually never any sort of shopping cart system on the site to buy stuff.
So, yeah...the social stuff went away, and now the entire site is defunct because apparently just being a shopping site didn't work out. I think I got that all right.

On the plus side, they did give us a lot of warning and allowed us to export all of our posts into a format that could be imported into blogger, which actually also conserved the comments. I posted my on its own blogger site and sometimes peruse it still for the memories.
