I promised that CommYou would go live in April, and we did manage to make that target -- by the end of the day Tuesday, the website was up in at least skeletal form, and the program itself was live. Indeed, it's already on its second release: unsurprisingly, the first release revealed one of those bugs that only shows up after it's been running for a while, and so I did a quickie 0.1.2 release yesterday, fixing that and a few other bugs.
(This is, BTW, where losing two months to building infrastructure starts to pay off. With a well-established test harness, build system, and all that, dropping a new release is *much* less traumatic and dangerous than it might be for a more hackish environment.)
I have to caveat that it's early days yet (indeed, I'm kind of annoying msmemory by how much I'm soft-balling things right now) -- at the moment, it has only a *tiny* number of features (maybe 20% of the ones I consider important), and I'm still working through lots of bugs. Still and all, it seems to be mostly working correctly, so you can now start having very simple LJ-ish conversations with your Facebook friends. And I hope for things to evolve pretty fast from here, with releases once or twice a week. My official goal is to be Useful in one month, and Cool in two. (And once people are finding it Cool, I'll have to take some time out to deal with scaling issues.)
So if you want to kick the tires and play with it, go over to http://www.commyou.com/, and you'll find instructions on how to install it into Facebook. Have fun, and I look forward to having you along for the ride...
