I can't seem to title my posts anymore. My title bar is there, but I cannot click in it. Huh.
I cannot type wonderful correctly the first time (though I just did). I always leave out the r. Just wondeful.
I always have to double check my spelling on recommendation, accommodation, occasion, and several other words with double consonants that I cannot think of right now.
Your and you're used incorrectly is a pet peeve of mine. As are there, their, and they're.
Also to and too. Sometimes I will type them incorrectly when I'm going too fast, but usually catch it in the proofread.
I often misspell words in comments on other blogs and catch it only after I've published. I'm so picky about this that I will copy my comment, delete it, then paste a new comment just to correct the spelling errors.
Typos bug me.
Apparently random posts about pretty much nothing do not.
