Positive effects of the Firefox spell checker

Anyone else notice that people are typo-ing lesser and lesser nowadays? Considering that most people whose blogs and e-mails I read generally tend to have a geeky bent, I don't think it would be terribly far fetched to attribute this to the Firefox's inbuilt spell checker. Case in point, I can actually understand my niece's e-mails nowadays. She's a web mail user and a Firefox convert (thanks to me). While a few months back, I was barely able to understand all the fracking SMS-speak in her correspondence, now I no longer mentally wince while reading her e-mails. When questioned about the gigantic improvements in her diction, I was told that it was because of all the squiggly lines that Firefox adds during its spell-checks :P

Such a simple solution. Such a widespread effect.
