As a very humble offering as substitute for my lack of grammatical posts, here is a very good post from Copyblogger. It’s a list of five common errors in writing.
True blogging and marketing copy is usually dumbed down a bit to a conversational style, which gives maneuvering room with grammar and spelling errors. But some are just so blatant that they make you look down right boob-ish.
For a more in-depth description, visit the Copyblogger post.
1. Your v. You’re – I pulled this one in a comment on one of my grammatical posts. Yes, just stupid.
2. It’s v. Its – This one is easy to avoid if you just read the contraction spelled out aloud. (It is instead of it’s.) If it doesn’t fit, use the other.
3. There v. Their
4. Affect v. Effect – Affect is not always the verb, effect not always the object. But they are almost every time. So use them accordingly.
5. Dangling participle – These take practice to spot. Even some of the best editors I know still can’t snag one of these.
