Is asking someone out via text message improper?

So, I’m curious! I know some would totally do this, but I’m up in the air about it. While I think it would prevent awkwardness for some people and make it easier for the opposite party to answer how they really feel, is it right to ask someone out via texting even if it is the way that most communicate in this day and age?

I am not sure that I could do this, just because I wouldn’t be getting a good ‘feel’ from their response without watching their face, hearing their tone of voice, etc. For me that might make it more awkward.
