In this gem, the author uses 'u' instead of 'you' in the middle of a sentence (which he has since corrected in some versions of this article) .I've never been a big fan of using the 'txtspk' shortcuts in any sort of document or article. It looks unprofessional, and in the case of this article snippet, it shows a generally inconsistency. Most of the time, the author uses a proper 'you', but slips up once. Bad form.
Side note: txtspk shortcuts are great when there is actually a limitation on the number of characters you can type, but not when you have a full keyboard and unlimited space. There's a time and place for that sort of thing, but it's not here.
