The way they've done it so far - yes, pretty much, except you can see all my entries in a specific category at once, instead of one at a time. So if I post 10 entries in "tech", you can see them all, rather than just opening them each up. (They're also better integrated with S2, something I've wanted for memories since forever.)

If they ever get around to it, there are a number of other benefits:
1. Global tags. Who else is posting using the "tech" or "RDF" tags?
2. friend-by-tags. Only show me the entries a person has tagged "tech" or "RDF".
3. Friends Group by tags. Only memebers of the "Boston" group can read posts tagged "Boston".

Stuff like that would make it cool. Now it just kind of sucks.
