I find it interesting how often people incorrectly use "then" and "than." I've seen and heard erroneous sentences like: "I'd rather do this then that." "Then" and "than" have completely different meanings. "Then" is used when talking about time or sequence. "Than" is used when comparing things.

Introduction to Grammar Guidelines
With texting, Facebook, and Twitter fast becoming main modes of communication, the new shorthand lingo that is developing will no doubt bring about a higher frequency of grammatical, spelling, and punctuation errors. The rules that define proper English seem to fade into the distance as more people forget them and replace that knowledge with acronyms such as OMG and LOL. The hope for this site is to reinforce proper English grammar and continue to encourage eloquent writing and speech.
