No longer an outsider: Dave Winer reports (celebrates) the availability of a Mac version of the OPML editor. (Download page here). I guess I now get to play. (However, I think I’ll wait until I’m on vacation in a couple of weeks to really dive in.)
At Gnomedex, I spent some time with Dave Luebbert, who worked with Dave W. on the initial release. Dave says also that Andre Radke has helped in getting the Mac version available. Thanks to everyone.
