Something I see more and more these days is the abuse of "'s" (apostrophe 's') when the context calls for pluralization, not possession, and definitely not verb inflection.
There are some cases where I'm not even clear, such as when using an acronym. But for regular, average everyday words? Sheesh.
If you're not sure what I'm talking about, perhaps if I rewrote a couple of the above snippets to read "when the context call's" and "average everyday word's".
These days what with weak Internet literacy abounding, that doesn't usually surprise me anymore. In fact, some are worth printing out, framing and hanging in a prominent area of the home.
But at the office?
One of the engineers at my company set up a wiki a year or two back. It's grown to be quite popular and rich with information. When I joined the company, there were just over 2000 pages. It's now about 3600 pages. Pretty sweet.
But yesterday I was reminded that people either don't know, or aren't paying attention, to the use of "'s". In fact, in the same paragraph I was treated to the same word twice, the first time with the correct plural usage, the second time with "'s"
This then gets into the whole issue regarding (poor) literacy in the corporate world. There was a good article referenced on Slashdot several months back. Apparently poor grammar in e-mails between companies (not just within companies) can inflame business relationships. And some HR groups are sending employees off for remedial writing skills training.
*sigh*
