genehack “It would be really nice if Advogato had some way of tracking certain diary pages, so you’d know when people updated.”
yakk was running something called DiaryWatcher, although it appears to be down, that would allow one to add advogato diaries you wished to see and only those diaries. I thought there were plans to add RSS watching as well.
Another posiability Randal Schwartz has a Perl script that pulled in RSS files and emailes any updates. The script could probably be easily modified to pull the xml versions of the advogato content, Ewan Birney’s diary is http://www.advogato.org/person/ewan/diary.xml, and send out updates.
