There are so many social networks, which ones would allow me to be most effective in communicating to my customers, as I don't have enough time to join all the ones I know of.

What are the strides used in online casinos?

How do you play within your bankroll in poker?

Should I follow lots of people who tweet words realted to my interests, or who are in my local area?

I often get messages that seem either automated or copy and pasted when I follow a Twitter account. Do you think we should all do this?

Which is best for me to start - or should I just do both?

Could someone please give me a brief explanation of why I should use Twitter? I just don't get it.
