I have never really used Computers(in minecraft that is), even though they are super handy and everyone uses them. The exception would be IC2 Nuclear Control at one point(but not for controlling a nuclear reactor ironically), and hopefully some day soon AE stuff.
I have only used RP2 gem tools once, back when they first came out, and never used them again because they aren't as good as diamond despite needing iron to mine(my main gripe with them).
I only recently found out that I can mine AE quartz with wooden tools, and thus can skip stone tools all together.
I have only been to the end once, and that was because I was using the Seed Dossier without any extra biomes, and thus knew exactly where the end portal was(right past the village you spawn looking at, in the ocean, in a single room fortress of badassery).
I have actually never made a map in creative mode, even when it first came out(NEI added a toggle button for creative mode almost as soon as that update was released), and have only made one test map(was looking into how good GregTech LESU's were) and even that map I spawned it in survival.
I haven't made a single thread on this site, but have recently thought about making one, but now can avoid needing to do so because someone has a open thread for people to hijack and talk in.
