I am old enough to have learned proper grammar.  I had to learn their, there, and they're, your and you're, two, to and too, its and it's.  I admit that I have a Master's in Expanded French Studies, and thus have a tendency to be picky.  I also admit to making spelling and typing mistakes.

I recently got a comment that had their and two so messed up it took me an hour to figure out two sentences.  I don't like to work that hard.  I am not likely to approve such a comment.  If you want to comment please make it easy for me to understand.  This  will make it easy for others to read too, and I might just allow two of your comments there on my profile.  After that they're (the other readers) likely to come back and read more of your comments. because it won't be a waste of their time.

If you're reading this please let me know.  It's just plain rude and cowardly not to show your face.  I love comments and nearly always approve them.  However, if its content is too nasty, vulgar, or hard to understand, it's not likely to be approved.
