good question, Roadie...gosh maybe we do have too many buttons to push here..

like and thanks are sorta the same if you think like me. yes i like what you wrote and thank you for writing it.. and thanking you means i like what you wrote. but then i like what you wrote means i agree with you.. and thank you could be just thanking you for writing what you wrote which i guess could also mean i agree but then thanking you just because i am thanking you.. hmmm
