Wait a minute, I'm a very smart person and I like games, I don't need CesarSuki to tell me how to choose my own freakin' games!. Well yes you are right, but MMORPGs are a big deal, and don't worry nobody is going to know that you read this.
This is not a fool-proof guide on selecting a MMO but hopefully it might help you learn a few pointers you must watch out for.

Theme
So what do you want to be? A quiet elf living in a mythical world? A brave knight that fights humongous monsters? how about a captain of a space ship?
There are a wide variety of themes to choose, and usually plenty of games in every category. There are also games specifically for a more mature audience like 2Moons where chat is not filtered and you can curse until your fingers hurt (the NPCs will treat you like trash, but anyway....).
Even if you are looking for a game for your child, beware that childish looking games have plenty of older, even senior, players in it. So follow the steps below to make sure your child doesn't get bullied or other bad stuff.
