What Methods of Contact do You Find Most Effective?

I am an organizer. If I see something really out of place or I see something that could make things more efficient or make things easier, I am one of those who thinks of those things. A lot. Kids keep me from being compulsive about it cause God knows they are all slobs! Lol!

Being the type of person I am,  I like to find the fastest, most effective way to do things, this includes communication.  I was wondering, what is the best way to get ahold of you to contact you or get information to you? (Phone? Email?  Twitter? ect?)

I look forward to your responses.
