Pretty much all of my time. We're a small shop. I network like crazy, both paid and free networks. If you have to choose, always go with paid. I also setup lunches with potential partners, clients and people who know people. About 3-5 lunches a week. It has a compounding effect and people will start referring others your way after a while.
My company's website is solid and it's purpose is to confirm that what I tell people is real. My online profile is also thought through.
Trying out new technologies isn't relevant, that's improving your skills as a SE. The others in my shop get to do this on a more regular basis since they hardly have to do any sales / networking.
