What is 'the cancer that is killing /b/'?

Every day, patriotic 'oldfags' complain about 'newfags' ruining 4chan's random board. Anything that contains a meme or a smiley face will cause a shitstorm of people posting "Back to reddit". In fact, /b/ has been redesigned to curb shit posting, and 'bring /b/ back to its roots'. Now, you cannot change your name, and you have an ID within a thread. Of course, this didn't change anything, and /b/ is still full of ponies and rage comics.

But are bronies and Redditors really killing /b/? No. The people who are killing /b/ are people who have been lurking the site for a few months and consider themselves oldfags. For some reason, wasting years of your life on that image board is seen as a good thing in the 4chan community, and if you haven't spend days in the basement on /b/ then you are an outcast. Anyway, /b/ has turned into an oldfag pissing contest, with people leaping at the chance to prove how much of their lives they have spend on the site.

Oh yeah, and bronies.
