I don't mine bitcoin. I just use the client as a wallet and I'm wondering that since I have to pay to process MY transactions... Is there a setting where I can set the client to refuse transactions unless I get paid? I apologize if this is a stupid question. I am new to this.
You are not a miner so this is not relevant. No worries.
Consider the 0.8.2 dust tx change this way: The MAF sensor on your car might have some fancy security torx bit holding it on. The only reason it has this and not a normal philips screw or hex head is that the carmaker had some deal with Torx so that Torx could sell more proprietary bits. It was unnecessarily complicated and required a special tool.
Gavin took the car and replaced the fancy torx bit with a normal hex head. So now (to mix metaphors) instead of reconfiguring and recompiling the code, something many miners would have no idea how to do (Since they don't own a fancy torx bit) they can just stick the standard hex wrench into their .conf file and choose which size tx to accept.
Now, we can argue all we want about the default being set to a certain value, but the increased configurability is not as controversial seeing as it already kind of existed... it was just a little obscure.
