Okay, I'll start. When I first came online, it was solely for entertainment. My first message board post was on BlackVoices-AOL (at the time) and NetNoir. I was an avid poster particularly to the religious boards. That is why I don't debate religion anymore because like politics it is a no win, never-ending, subject. I bore easily...
Nowadays, my online use is mostly for information gathering. AAorg is the only message board that I frequent for obvious reasons - I enjoy reading the minds of the poster's here. Aside from that, it is a wonderful opportunity to exchange with people from various parts of the world.
In addition, there is a wealth of knowledge out here, and you get to choose what you want to view and absorb. If I don't like something, "click" poof its gone. I love having that option. Sometimes I wish I could do that in real time.
Overall, my Internet experience has been what I've made it, rewarding.
