Last but not least:
Twitter @4pm on Friday. Check out hashtag #aptchat. Good "stimulating" conversation -- just to paraphrase The Training Factor from a chat a few weeks ago.
And by all means -- ATTEND CONFERENCES! This is a people business -- and people like to meet people in person. Social media has come a long way -- but will never surpass a handshake, a personal conversation and a good meal -- or cold drink!
If you need more resources -- I have a ton -- send me a note.
Hope this helps! Happy New Year!
