My mission is the absolute obliteration of the semi-colon.
No reason for its existence whatsoever. Many more elegant and easier-to-read ways to accomplish the same thing. (see endash and emdash) Visually, reading a semi-colon is like stumbing over something on the ground. It ruins the flow of the content.
I don't agree. To me, a semicolon and a dash convey two very different kinds of pause. A dash is an abrupt break -- intense, sudden, sharp. A semicolon is a gentler, more thoughtful pause; also, it conveys not merely emphasis, but transition from one thought to another.
Also, as I understand it, a dash is more or less gramatically equivalent to a comma. You use it in the same places you'd use a comma, but in situations where you want a sharper or more emphatic divide. Thus, using it in place of a semicolon would create a run-on sentence.
...and Copywrite for Copyright.
Oh yeah, that one really bugs me. I mean, I can understand it, since people associate it with writing, but it's missing the whole point of the word, which is that it's a right, a legal entitlement. It's the right to reproduce or distribute a work for profit. Not to mention that "copywrite" already has its own distinct meaning, i.e. to write copy.
