over the last couple days, i looked at appengine for the xfn spider. i learned just enough python syntax to be dangerous. i learned some annoyances of python. len() and str()? what is this, php? i learned django is not as far along as i had expected. no constructor or callback on model creation. the svn docs say its there but not documented yet.
the real killer is that appengine does not support background processes. 99% of the work that the xfn spider does is in a background process. i still think appengine is cool but i'll have to wait for background processes and maybe by then they'll have java support (and therefore jruby support)
so maybe i'll fixup the ruby xfn spider instead
