I'm writing you from lovely Austin TX as we wrap up our exhibit hall stuff at SXSW. It's been super fun and a LOT of people seem really excited about concrete5. We've met plenty of directors of huge companies and consultancies, new media reporters, all sorts of folks, but often its the Joomla developers who have the most amusing response. After starting slow with a "I guess I'll check it out" and then going through a couple "Holy-Moly its that easy?!?" moments they end up leaving somewhat disgruntled. "Where the h#ll have you guys been? I just wasted 2 years learning Joomla and it took me 10 minutes to get as far as it took me 2 weeks to do in it!".. That's good stuff.
Thought we should also let everyone know we FINALLY re-did our documentation and it's waaaay better now. We still have some pages we want to add, but now everything is nicely organized and makes sense with a cool slidey jump nav. We even hooked it into our forum system using some tags and a "helpful answer" system so instead of those annoying guestbook comments that just grew out of control, our doc pages can start discussions that remain encapsulated but are still searchable.
concrete5.4 is out as a Release Candidate now so you should certainly check that out and let us know if its ready to ship. We think it just about is.
Thanks for your attention,
ps: here's pics from SXSW.
