SpicyLinks Ning App
SpicyLinks is a link-blog aggregator, generating a "best-of" feed from a set of links-oriented input feeds.
It currently runs as a script, from a hand-edited OPML file. It would be cool to make this more web-based -- in other words, turn the script into some form of aggregator web-app.
Idea: use a net-accessible OPML file as the input, e.g. at http://www.shareyouropml.com/
Idea: host it as a Ning app on http://www.ning.com/ -- however, would require a port to PHP, a lot of work
Idea: ensure that source feeds are cached globally; e.g. if 5 people list waxy's feed, it gets retrieved only once per 15 min period and cached globally.
