Welcome to BookCrossing. The Alot is Better Than You at Everything. As a grammatically conscientious person who frequents internet forums and YouTube, I have found it necessary to develop a few coping mechanisms.
When someone types out "u" instead of "you," instead of getting mad, I imagine them having only one finger on each hand and then their actions seem reasonable. If I only had one finger on each hand, I'd leave out unnecessary letters too!
