Admit it: You’ve looked through your Facebook or Twitter feed and cringed when someone uses the wrong your/you’re, its/it’s or they’re/there/their. I know I’ve done it.

Here are 4 more mistakes to add to the list. If you’re doing this, don’t worry. You can fix it. I won’t tell anyone:

1. He he vs. hee hee

A lot of people are laughing the wrong way on the Internet. Laughter is not the pronoun he. If you’re saying “He he he!”, what you’re really saying is “A male person a male person a male person!”

There’s actually another e. It’s hee hee.

2. Whoa or woah?

People are also expressing shock or surprise the wrong way. Crazy, right? It’s actually spelled whoa. You know, like what cowboys yelled to stop a horse. “Whoa, Nelly!” If you don’t remember which spelling to use, just write wow. That one’s hard to screw up.

3. Decades and the apostrophe

The poor little apostrophe. It’s misunderstood and abused! One of the uses of an apostrophe is a contraction. If you’re using a contraction, the apostrophe is taking the place of something that’s missing. When you list decades and leave off the first 2 numbers of the century, the apostrophe should take their place. So 1990s becomes ‘90s. If you’re using the apostrophe between the numbers and the s, you’re making the decade possessive. And that’s just weird.

4. Using symbols in a hashtag

I don’t think this person was deliberately trying to use an exclamation point in her hashtag. But you can see that it’s right next to the words in the hashtag and isn’t part of the highlighted text.

A hashtag on Twitter – or really on Facebook, Google+, Pinterest and Instagram because you can also use hashtags on those networks – is the pound sign in front of a word or a phrase that uses letters and numbers. Twitter will take whatever you put after the pound sign and turn it into a clickable link that you can use to find other tweets with that hashtag. But it doesn’t use numbers or symbols. So don’t even try to use them in your hashtags. They won’t work.
