Beautiful -- and I promise I'll be nice. Though, couch's sound design means
there's nothing I can do to your system (other than drop your dbs, which I
won't touch obviously). Are there any other security concerns in that light?
I've left my instance wide for a few friends to play with -- perhaps I
should have asked this earlier.

I know -- I *was* poking around. I feel like such a peeping tom, though it
does have a TI-82 feel (my high school baseline -- am I dating myself with
that one?)...

I noticed you were still action-free -- but to do it unobtrusively I'm going
to need the action server for every request -- and based on the req obj it
can decide whether to pass the whole template or just the small piece that I
can jQuery.load into the dom (I haven't been able to examine the req yet but
I imagine I'll be able to get to the jQuery X-Requested-With header it
passes in). But yeah, if I squash the unobtrusive thing I'll probably only
need an action for periodic feed updates (any ideas on a good cron strategy
for something like an action server that would take through replication?).

I already tried it -- I couldn't help myself. An hour ago all I got was a
black screen -- now I see some action down below (other than the tweet form
everything gets cut off on Firefox Ubuntu Hardy).

Screw cosmetics. Don't forget there's always a better designer out there --
justTI-85 the thing and that's easy enough for someone else to fix!

I'm a python guy but I've really grown to appreciate the beauty of
javascript. Frankly I'm starting to really miss js anonymous function blocks
every time I try to cram a lambda onto one line (among other things).

But this whole notion of not having to worry about deployment...at...all.
Just thinking about it makes me want to almost cry.
