Obviously you didn't actually try what you suggested, if you had you'd have found there are plugins for JSON and XML and probably a few other formats, but was hoping ST2 would have what textmate and eclipse has had for a long time, code formatting, java, XML, xsl, JavaScript, c etc.
I know you're new here, but a little reminder about etiquette, even if you haven't gotten laid in a while, the community here is based on people being helpful rather than trying to be superior. The problem with that attitude is that it backfires and just makes you look insecure.
