A vast majority of people are just like that, very minimalist with their texting. I agree that it's annoying (maybe it's annoying for us because we're used to message boards and having to articulate our thoughts into words (for the most part) so when you do all that and get an "ok" back then it's frustrating) but you have to understand that most people grew up with texting and calling and for most people texting is a last resort/quick option while calling is their primary way to communicate. Most people aren't used to writing their thoughts in a text message so they just try to write a response as quick as possible.
