I've been disappointed by ignored emails and texts a few times. But for a couple people it was just that they were not comfortable with technology. My sister used to be very bad about this but i guess she has joined the digital age and she's great now. Also, i find people really have to go out of their way to sound warm and friendly in print. If someone is not clear that they mean things positively it comes across as negative.

I don't have a lot of experience communicating online tho. These are just a few things i noticed in the little bit i do.
