What's the difference between @foo and #foo? Enough said.

[jsemrau]

@foo refers to a user and #foo to a topic. What's the problem?

[talmand]

Seems the problem might be a lack of understanding that @ and # are two different characters that might have different meanings.

Kind of like how + and - have different meanings, complete opposites actually, but people just get them confused all the time.

I think that flushandforget's point was that not he or she, but the vast majority of users, do not recognise (or do not behave as if they recognise) the difference.
