currently, lj optionally sends emails whenever a comment is posted; i wonder if it would be beneficial to send an IM message (ICQ, AIM, MSN, Jabber, YHOO) instead. IM Msgs are more immediate and the lj emails could pile up if a user receives too many comments. we could use jabber (jabber C API or Net::Jabber) to send IMs to any jabber-supported network. wouldn't be too difficult to write an abstract LJ::UserMsg layer that would send a message as email or IM depending on user preference.
since i have plenty of free time now, i am planning on implementing this. i am looking for any pros, cons, or any suggestions. maybe somebody is already working on something similar..
[ oh, i saw the lj camp at brc but unfortunately didn't get a chance to swing by. will do next year ]
