I'm no fan of STB, but are you guys really arguing that it isn't beneficial to help a 15 year old kid to spell correctly? Simply put, when I was 15 I knew the difference among:
who's, whose
its, it's
there, they're and their
are, our
won, one
to, too and too
knew, new
or that 'a lot' are two words, not one.
Is it really too much to ask that people use the correct words when trying to communicate via text? I struggle with spelling words correctly everyday and when I'm unsure, I take the 15 seconds to look it up.
Correcting someone isn't necessarily an insult; it can be just helping them to learn the correct way. I love it when people correct my spelling and grammar and I try to learn from it.
Stop using the idea 'It's a message board - grammar and spelling don't count' as an excuse to dumb down the board or kids who are in high school or college or beyond who really should know better.
