I just read about that and joined one yesterday, though. I ran it for an hour or so and made a ten-thousandth of a bitcoin or so, at which point I calculated that it's probably not worth the electricity and shut it down.
You are probably not an owner of a recent ATI video card, then. Or you joined a pool that showed you how to CPU mine, that's not the right way at all.
If you go with today's exchange rate, the Bitcoins I've collected mining since January are worth between 3 and 5 dollars (US) a day. I only recently shut down my BTC mining to try Litecoin, which is reported to be about 4x more profitable to mine.
The profitability of mining has gone down sharply in this time, if you ignore the fact that the exchange rate over time has made up for this fact. The coins I mined in January were worth more because there were more of them (and I didn't cash them in.) Last clean 11 day sprint of mining before the LTC experiment resulted in 0.2652BTC, same as the 8 day sprints in January.
EDIT: I forgot to mention I have a video card that I bought from Best Buy about a year ago for $160. Not exactly top of the line.
฿0.10 is currently USD$13.47, that's almost double minimum-wage. I'm having a _really_ hard time believing your computer uses USD$13.47 of electricity an hour.
