Would you say, "Scripts that make ROM writable, now that's a feat!" to the person you quoted in to his face? If so, you are a rude person too.

The #wellactually brigade is the second-worst part of the internet.

(The frothing racists and sexists are first. But it's closer than it should be...)

Huh, I didn't realize that was actually a term. Learned something new. (For anyone else who hadn't seen it, http://tirania.org/blog/archive/2011/Feb-17.html)

I'm simultaneously glad and horrified to have read that. Horrified because I'm frantically thinking through the last 20 or so conversations with my friends in the pub to see if I did an annoying "Well, actually...", but glad because I'm going to consciously avoid doing this in future.

You've pretty much summed up my reaction as well.

Holy shit, are you serious?

No, I was being ironic

This "Well, actually..." would also be rude in the real world.
