You’ve probably seen people use the # pound sign in Twitter posts, and maybe you’ve wondered what they’re for. They’re called hashtags, and they’re mighty useful.
What’s a # hashtag symbol mean?
A hashtag is a great way for people to organize around a topic on Twitter. Think of them as categories, or ‘tags’ that can be used to identify tweets related to specific topics.
For example, if you search for Bend (without a hashtag) on Twitter, you’ll probably get something like this:

Anything with the word “bend” was found. However, if you search for #Bend, you’ll find what you’re looking for:

Hey, it’s Bend, Oregon! If you’re looking for (or talking about) activities in Bend, use #inbend:

Ok, that’s cool.. so how do I search Twitter like that?
