How's it spam? I select people/accounts I want to follow, and tweets from them show up in chronological order in my timeline. Sounds brilliant, someone should get on that!

So no @ and no #, ie no way to discover what people you're not following are talking about unless linked by someone you do follow?

# — sure, allow it. If you ask for all the comments that mention a hashtag, you're requesting a drink from the firehose, and you should get it.

@ — maybe allow it, but only for users who mutually follow one another.
