I simply don't understand why it's so difficult to form a proper sentence and nt tipe like dis 4ever.
My gear grinders related to typing:
1) People using aformentioned shortcuts: u, 4, y, etc.
2) people not spacing after fullstops and not capitalising.it makes the post near impossible to read.
Other than that, I don't really care. If you can get the point across, and the post is legible, I don't care if you're using subjunctive when you should use pluperfect, or whatever. Oh, and it's obvious when English is not somebody's first language. The post looks very different from that of a very lazy native English speaker. To be honest, those can be a little hard to read, but I can hardly blame the poster for that.
