Thank you for pointing out those mistakes Doug. While we're on the subject, I would argue that this statement needs more work.

"And, it's not just incorrect usage of apostrophes, either (its vs it's, there/their/they're), but sometimes an entirely other word has been substituted that changes the sense of the sentence! Also the use of text-speak in regular postings–aaaah!"

While it's not technically incorrect to start a sentence with "And", it adds an air of informality. There are better choices. Simply starting the sentence with "It's not just…" would have been sufficient to avoid the awkward use of a coordinating conjunction. The final sentence could benefit from a comma being placed after "Also". Finally, closing the sentence with the use of the expression "aaaah!" is arguably simplistic and vague. Perhaps you mean to express frustration? If you are trying to explain a complex set of emotions and lack the proper vocabulary, I suggest you investigate those feelings and find the proper vocabulary to express them. The reader will gain a more accurate insight into what you are trying to say.
