I think we all need to look at our posts... actually read it and think about what it would feel like if that post was directed at you. Typically, my posts are edited two to three times before I put them up unless I'm sufficiently tired and shouldn't be pretending to be social because I'm brain dead. If your post looks like a rant... it probably is a rant and is probably lacking constructive criticism and a bit of structure that makes it easy to read/understand. We all make mistakes, admitting you make mistakes is the important part.
