I’ve been experimenting around with TwitterPad to archive Twitter streams from my class’s backchannel. Right now I have it configured to update a single page every four hours. It works well for a day or two, and then suddenly all of the tweets disappear. I visit the page and nothing’s there. If I run “reset” the page will repopulate, though only with the most recent tweets. I lose the earlier ones I had there. Any ideas?
