You guys are too damn much!
Whatever happened to the saying "to each his own"? "Different strokes for different folks"? etc
If a chick has low interest you don't stand much of a chance of raising it via ANY METHOD whether that be texting, calling or waiting outside her house at 3 AM. She doesn't really dig you, end of story.
If a chick has high interest I think, depending on your "text game", you can do yourself a disservice if you're texting too much, responding right away, seeming needy. But if you use restraint and keep working the mysterious angle you should be just fine.
Texting is not an option these days especially if, as others have said, you're gaming a girl in her 20's. They text, that's what they do. The key is to stand out from the potentially dozens of orbiters she's playing pen pals with all day. This is where restraint/not responding really gets her hamster working. She'll be thinking:
Why hasn't he responded?! All guys text me right back?!?!? WTF?!?!?
If you're not a texter no biggie. If you like to text then by all means do your thing. I have no clue why everyone wants to bicker about this as if there is a concrete rule somewhere. Texting is a tool, nothing more, nothing less.
