A Chance at a Personal Introduction Using Question and Answer Sites

I have been really getting into answering questions on LinkedIn's answers section. I have the technology areas on my RSS feed so when they come in. I find I learn a lot from some of the questions posed. Not just answering questions for people.

I have also have really made a lot of connections doing this. I was just thinking about what a wonderful opportunity it is to make one on one connections with people and make a good first impression by helping them solve a problem.
