followusontwitterWe recently explained what they call a “hashtag” on Twitter: It looks like this: “#.” It’s used to organize and navigate your way around Twitter. Typing #BillGates when you’re logged into Twitter, for example, takes you to Gates’ Twitter page. A reader wrote in to say he loved the explanation, but what about the “@” on Twitter?

The “@” is used when you’re replying to someone else’s post. Click the reply icon and Twitter fills in the @ along with the person’s Twitter name. You can also use “@” when you want to reference someone or something. For example: Suppose you write something about physics and want to credit an article in Scientific American. The magazine’s Twitter name is “sciam.” So to reference them, you would simply add “@sciam” to your post.

Our Twitter handle is “oncomp.” So Joy’s nephew tweeted: “@oncomp “Thanks for the smoothie #vitamix.” In plain English, we got him a Vitamix blender for a graduation present so he was saying thanks and then referencing smoothie recipes on their home page.
