Stop taking this so seriously! Its a damn twitter account. Who cares what people close articles with. The more people that follow them the happier they are. To each their own.
When someone ends an article with "You should follow me on twitter", they're being arrogant obnoxious and rude. If their only aim is to get weak minded sheep to follow them, then fair enough. But put the "You should follow me on twitter" link at the top so other people can just ignore the article.
All of these devices are just ways to try and get people to spam for you. Ooops spam is so 1.0. I mean "go viral".
