I've Facebook Messenger on Android and use it to keep in touch with friends. Especially those who have made their Facebook account as primary account of communication. To make matters worse, some of them replies to my emails, not via email, but from their Facebook accounts to mine without any capitalization and a lot these "....." with varying amount of dots in those strings. Once in a while I do check my Facebook account on the web. Sometimes I upload few pics for my (all) friends to see, otherwise my photo sharing is restricted to Dropbox mostly. I tried to leave but couldn't, for the same reason as yours.
