I regularly message/email my group of contacts asking about job openings, but they always say some form of "sorry, I don't know of anything right now" every time. Could be just a lot of bad luck and timing, I guess? Buying someone a drink becomes surprisingly hard to do with only $48 in the bank. Some of them I can't meet locally, also, because they have moved out of state.
