Microsoft enters Enterprise IM

The Register has a piece on Microsoft entering the enterprise IM space next year. Oddly enough, the article mentions AOL and Yahoo! as potential competitors but does not note that Lotus is currently the dominant vendor in the market with SameTime. That says something about Lotus's visibility these days. I used the system when I was there and (to my surprise) really liked it. It turns out that the killer feature is "presence", the warm fuzzy feeling you get when the little green dot lets you know your friend is online. Who knew?
