It does annoy me when people use "like" to mean "as", or when they use a comma where a semi-colon is more suited.
I know descriptivists will say that this is just how language evolves...etc
While I can easily accept that as true, I don't know why people are so sanguine about it. It's intellectually lazy. E.g. - if we were to replace semi-colons with commas, there would be no difference between the short (phonetic and conceptual) pause indicated by a comma and the longer one signified by a semi-colon. And that would be a loss of nuance. Yet no one seems to care. Where are people's standards?
That has been your weekly grammatical rant from moi.
Also, while I'm at it, I get slightly, almost (but not quite) imperceptibly annoyed by tense mismatches.
I saw something in the paper today (it's meant to be a decent paper but I think they fired all their editors in a cost-cutting thing) that said, "Since Bush's election in 2004, I thought about this issue..." - of course it should have been "I've been thinking about this issue" not "I thought". Or you could have kept the "I thought" and changed "Since" to "After".
I'm not trying to be unnecessarily nitpicky - the tense dislocation genuinely makes my brain skip a beat when I read it.
