I appreciate the benefits that the quality filter brings to the site, but I've noticed that posts are still making it through with a lot of lower case 'i' instead of 'I' and 'u' in place of "you".
I understand the acceptable practice of using abbreviations while texting, and I accept that these uses are permissible when scratching out a quick message to a friend or loved one that you'll be late for the movies, but I think the 'i's and 'u's detract from the professionalism of the questions and answers on the site. I think there are many that agree with me in general terms, as we wouldn't have the filters in the first place if this weren't the case.
I don't know how the filters work (I can make some educated guesses, obviously), but I don't need to know. I'm asking if it's possible to strengthen them just a bit more against these two cases. I don't mind editing posts where I see 'i' and 'u' being used, but I think helping people fix their own posts at the point of origin is even more powerful.
As has been brought up multiple times, "X Language and Usage", as well as upcoming "Stack Overflow (in X language)", sites are vital to the network, and some of these languages contain constructs using 'i' and 'u'. Obviously, a filter containing such a rule on these sites would be counterproductive, so I'm proposing this for English language sites only.
