I'm a tiny miner, averaging a little under 200MH/s on a 5770 I already had. Kinda wish I'd looked into mining 6 months ago, but oh well.
I have been averaging 210MH/s on each 5770. 300MHz memory, 950MHz core, 1.1V. I bought two for $100 each when I found out about bitcoin a little over a year ago (I only had nVidia cards back then). Mined in a pool for a bit until I had $200 worth of BTC to justify buying the hardware instead of coins directly, then I mined solo when the pool I was in kept going down because of lack of maintenance.
I've been mining away on a 5770 for a year and a half now.. I remember thinking how bad the jump up to 500,000 diff was.. doesn't seem so bad now. But I still missed all the real fun before that when the GPU miners first came out. It's been amusing to play around with though and hope it continues to grow.
I learned about bitcoin after GPUs were already mainstream. I then forgot about it for a while with my 2x5770 just running in the background, and last week just used the 2 lucky blocks I found to pre-order a bASIC. Haven't been paying attention to difficulty, I didn't even notice I found the second block solo until 3 months after when I needed to reboot my computer.
. I have high hopes for the future of bitcoin. In about 2 weeks I will be ordering a 60 g/hash device. Have 1 jally on preorder. Mining its a growing process I believe. Start with a few devices, and continue to reinvest. We'll see how it goes 
speaking of that, I think there are zero people who aren't around my age (mid 20's) in the bitcoin community, rofl. This reminds me of DDO.
