If you really are paranoid about those transactions, you should blur the dates and times as well. They could be used to track down these transactions on blockexplorer. It wouldn't be easy, of course, but it's doable. Still, if you want to remain safe. You know. You can never know who could be out to get you.
I first found out about Bitcoin sometime during early winter, back in 2010. A friend at my university told me about it, and managed to get me interested. I put my server computer to work and mined for a while before I got too lazy about it, thinking it wasn't really worthwhile. Now I regret that decision.
Since then, I 'rediscovered' Bitcoin early this month, as the value had increased by quite a bit. I set two computers to mine, one with a 5870 and another with a 5850, but I was in a bit of a hurry to go visit my parents and attend a funeral, so I was unable to optimize the setup properly before I left town. Regardless, I can reach roughly 600 - 700 (5870 at 310 - 360, 5850 at 290 - 340) megahashes per second without a lot of optimizations, so there's that. Tomorrow I'll finally be returning to my own apartment, though, and I can start fiddling around.
I managed to set this up on 11.06.11, but there has been some downtime every now and then. Regardless, I've managed to acquire 2.5 bitcoins since then.
