If you're a Twitter user, there may be certain people you don't follow so you can't see their tweets.

And if you're like me, there are some topics that, from time to time, I would just as soon not be subjected to. I don't necessarily want to unfollow the people who tweet about these subjects (but I don't want to see all 2,478 tweets about their love for whatever sporting event their overdosing on).

One of those events may be South by Southwest, which is being held this weekend in Austin, Texas.

If you'd like to block certain subjects on Twitter, this article tells you how.
