Actually, I now seem to be up 365 virtual dollars on the Buzz Research prediction market (Suddenly I'm wishing this was real money :-)
Mainly, it's thanks to JotSpot, which has climbed phenomenally after the release of JotSpot 2 and their accompanying media binge. OTOH I've invested a lot of my virtual money in SocialText, and despite the Open Sourcing announcement, they've fallen. I suspect people on the market think they should be in the wiki sector but don't know where. So they work on the principle of having the succesful wiki company. Because Jotspot is going up, they're trading in their SocialText, TWiki and MediaWiki shares to buy it.
Me? I'm investing in them all.
When I started, I lost money on Laszlo, RSS and OPML but these have, slowly, climbed back and are now higher than when I bought them. Two reliable investments are "microformats" and "WordPress". I was surprised by the latter. I thought it was worthwhile, but didn't expect much. But it's creeping up and up.
The disappointment is Eclipse which has fallen. Not sure what's going wrong here. Maybe it's billed as a Java Development Environment and Java is falling? (Actually why no programming language market?)
Right now, I can't think of any rival to Eclipse. Unless something surprising happens, what other comprehensive free IDEs are there which can be adapted for things like Python and Ruby?
Against my heart, I haven't invested in Emacs, as I'm not sure I see a future for it. Even Vim seems more dynamic. But I could be wrong about this. I'd like to be.
