I'm with you for the most part. Basic punctuation and grammar shouldn't be tossed out due to sheer laziness.
Honestly, I often try to be a bit creative with my posts in tems of things like imagery and I do appreciate a well written post as well. Both are few and far between.
On the other hand, I know I am guilty of making paragraphs from a single sentence but this, as was posted above, partly comes from writing business emails and partly as what I believe to be a now acceptable practice in the new interwebs era.
The English language is one of he few that could morph with the interwebs and reflect the changes this new method of communication. I expect that this will onl continue in the future.
