There's a fair amount of content on the site which can 'update' on a frequent basis. Threads; developer journals; columns; GDS entries; etc. It is reasonable to assume that a user will wish to track developments in a particular 'channel' of content (where a 'channel' is one of the frequently-updating entities I mentioned, like threads and columns). So, how about we drop the bookmarking system, and provide 'content subscriptions' instead? A unified interface for watching threads, columns, news items, GDS entries, journals, and any other channels that we establish in the future. Eventually what we get is almost a personalised start page for each user, with "recent updates" in all their subscribed sections.
