I understand what your saying, and I agree. A section with a million guides on very specific circumstances is not as effective as a thread with links to other threads that cover those 1 million circumstances in 10 different posts. I agree. However, I was looking at a bigger picture. There are quite a few different guides one can write and still be "general".
I would say, that a guide on OC'ing an Intel chip is general enough to be put in a different thread than a guide on OC'ing an AMD chip. The differences in technique are significant enough to warrant their own threads. Right off the top of my mind, I could name 10 easy guides (that may already exists or not) that are general enough to provide that portability you talk about:
-Installation Efficiency: No crapware, registry leftovers, disk fragmentation, etc.
-Dealing with a Blue Screen of Death
-Cable Management: Tips & Tricks
-Home Network Set-up
-Network Troubleshooting: Common Problems
-Assembling Your First Computer
-Multi-Booting
-Multi-Monitor Set-up: Pros/Cons, etc.
-An Introduction to SLI/Crossfire
-RAID: Storage on Roids!
-Benchmarking: Programs and Results
-OC'ing to the next level: CPU lapping, pencil mods, hard mods, and more!
I mean...I could list stuff that many of us could write about forever! These are all general topics that people can write guides on. They're not hard to write, I just feel like people don't do it because they want their stuff stickied; and mods can't sticky everything else "immediate need" posts wouldn't be on page 1.
