Mmm...always easy to pick holes in grammar and how a post might be worded, but if you can read it and understand it without having to continually re-read a sentence or paragraph, well, you can't be doing that much wrong....spelling notwithstanding though!
A mate of mine showed me a letter he had composed, it was absolutely flawless, correct in every grammatical detail...and utterly dead and lifeless as a result.
Recently I...er..sort of re-wrote and fleshed out some coursework my partner had done, some of which she wasn't at all happy with; however, in it stayed and with some reluctance was duly handed in...and got her top marks as a result! Yeah, yeah, bad of me I know, but it worked.
Websites don't have to be boring or look like they've been penned by a Victorian scribe, sat at a wooden desk using a quill and inkwell.

Bah! Got carried away there with my vision of a scribe, had about half a dozen lines of descriptive narrative to delete...sigh, see? I'm doing it again!
But if any of you have read this and smiled, even a little then you get my point; grammatical precision isn't always necessary, even when wishing to give the impression of professionalism.
Er...not that I was trying to with the above I might add!
