I used to HATE grammar police.
My own spelling and grammar are improving a lot, so now I'm starting to understand why incorrect spelling and grammar bothers some people so much. Being slow in learning English I'll willingly admit to being terrible at times and far from perfect now, but when you do get glaringly obvious errors it's like nails on a chalkboard.
I improved my English because I spent so much time on forums having the grammar police on my back that I started using Microsoft Word to check my posts before posting to avoid people using this as an excuse to undermine me, this helped a LOT by showing me my mistakes as I typed. Seriously, grammar has always been a blind spot for me, using Word in this way helped me more than anything else ever did.
Why don't others do this? Or if you know your English is poor use the spell check function on Google Chrome (so useful!), then you can post without bothering others, having the grammar police bother you, or having the pettiness in forums of having people ignore your arguments based on a typo or a mistake in your grammar.
