don panoccio has me beat. i guess there is one thing he tries harder. but then i don't twit, i mean tweet.
My most recent one that I caught was spelling pharmacological as pharmalogical. It's not really embarrassing because the post was informative and I typed it on my smart phone in kind of a rush. I've mentioned before on this site that I seem to be more prone to errors on my phone for some reason, it's kind of an interesting phenomena really. There are some posts of mine I come across with a spelling typo and I question whether I spelled it that way or it's the autocorrect/predictive text's error. I tried going without those at one point but I came to the realization that I prefer convenience over accuracy here. Most the subforums I would care to be formal in are barely active these days, so it's not a high priority to me.
