Im probably online around 8-10 hours a day M-F, and anywhere from 0-12 hours a day on the weekends... usually if Im not working on cars Im "researching" or talking about them on the internet. I try to fit some sleep in there, too. Ha, I have actually fell asleep at home in my computer chair several times, waiting for an ISO to download, or an OS to install, etc, at like 4AM.
I dont spend much time online anymore. My car doesnt need much for parts anymore really. I've replaced most of what needs it other than suspension.
My day consists of get up at 7am. get my kid up, feed and get to school by 8am. Drive down the road to work by 8am as well. I get a 1 hour lunch so by time I get here I can spend about 30 min online. I get home at 5"30-6pm and spend about another hour or so online and thats it. I watch some t.v. and play FFXI online for a while, Im hooked on that game. I guess if you count that as being online than im on for a good 4-6 hours a day
