I’ve just been having a bit of a play with this. Wow, it does a lot, and it looks to be really great — but it’s not a blogger, so Crossed Wires will probably be safe on Polarblog for a while yet.
It really looks to be an impressive piece of programming. It’s produced by a company called (surprisingly) Metadot Corporation, on the apparently quite successful model of “give a Free version to the community, but offer a pay-for version and support contracts”.
It does extensive content management, calendaring, polls, email forms, you name it; and it’s all managed through a browser.
Hopefully I’ll get a chance to do some more extensive testing over the coming weeks.
