Accept "updated" pings from remote blogs
Short, concise description of the idea
Allow a setup whereby LiveJournal will accept "journal updated" type pings and then poll the updated feed.
Full description of the idea
As I understand it the main motivation behind syndication points (the cost associated with subscribing to feeds) is that it costs LiveJournal to poll remote journals that may not have been updated.
When a remote journal is willing to cooperate with LiveJournal, though, it would be able to send LiveJournal a notification that it has updated using the normal pings now to notify sites like weblogs.com.
Under this suggestion LiveJournal would only poll the remote feed after receiving a ping from the source, saving quite a lot of useless attempts.
I would drop the syndication cost from such feeds since they avoid the expense to LiveJournal.
