With the advent of texting and online social networking. There has been a dictionary of new words and acronyms, based on abbreviations. I have noticed that I will misuse there, they're and their, hear and here... and the incidence of my grammatical errors has increased with the increase in longevity of my online and text communication. I understand this is anecdotal, but I am wondering:Are there studies showing the effects of online social networking and texting on people's  written language skills?
