If there is an area of my writing I know is a potential pitfall -- aside from my comma usage paranoia and tendency to lean a little heavy on the ellipsis -- it's my spelling skills.
I know the whole "I before E, except after C" mantra, but it's surprising how many exceptions there are to that rule, and my ability to find them.
Microsoft Word's auto-correction is both a blessing and a curse, because it fixes most of those mistakes for me. Unfortunately, it takes me that much longer to burn the correct spelling into my brain. Not to mention, I feel lost when MS Word isn't a fallback option.
Perfect example of this is a comment I just left on Terry's awesome blog, A Writer of Wrongs. In my comment to him, I was using this whole analogy that revolved around being a fish (you have to read the comment to understand. It makes sense, I swear). Anyway, right at the end I wanted to use the word barracuda ... except I didn't know how to spell it correctly.
Blogger, unlike my beloved MS word, doesn't really give you much help other than the nasty red, dotted underline that says "Hey Idiot, this isn't a real word, ya know." After several failed attempts at guessing a correct spelling, I finally gave up and went with shark instead.
Then I decided to look the spelling up in the dictionary. It took me forever, because my freaking "Hooked on Phonics" style brain was thinking the second letter was an "E"... and when that didn't pan out, I went to "U". Ten minutes later, when I went with my third choice for the letter "A", I found it.
Normally, I think of myself as a relatively intelligent person, but at times like this I find myself questioning that notion.
I'll tell you one thing ... I doubt I'll ever forget how to spell barracuda now! In fact, I wouldn't be surprised if that darned word doesn't find a way to work itself into every future manuscript I write.
