Not that I've been obsessed or anything...
Anyway, Nick Bradbury has returned from his Thanksgiving break and instantly hits the nails on the head:
"To me, the point is that every aggregator already supports OPML import/export. Whenever someone tries a new aggregator, the first thing they do is import their OPML. Which is better: asking a user to import two files - one for their subscriptions, and one for their attention data - or a single OPML file which includes both the user's subscriptions and attention data? Your OPML subscription list already contains attention data in the form of the feeds you pay attention to, so it's not exactly a stretch to put more attention data in OPML.
FWIW, my preference would be to define an attention namespace for OPML which contains a subset of the same attributes that are already defined by Attention.xml. After all, the Attention.xml authors have already done the hard work of defining the important attention attributes, and with their permission, we should build on that instead of starting over (and as an added bonus, using the same attributes would simplify converting between the two formats)."
I, not suprisingly, support this approach 100%.
Let's just do it now.
