i'm a text nutter - always reply to the first message i'm sent as part of a convo - not necessarily after that cos the convo has to answer some time!!! soooo many of my friends work in call centres, shift work etc that it's almost impossible to contact them on the phone - so text is our medium for catching up.

always reply to birthday messages and things - ummmmm, always reply if there is a question or if i'm being told someone is late, on their way etc - it's just polite to acknowledge you got the message!

i very rarely make phone calls cos i don't see the point in leaving voice mail messages and then someone having to call back - if it's important, i'll call - but so little of my communication is important enough to warrant a phone call! lol
