Honestly, if you want to pick up bits and pieces about everything... You'd be surprised how much you learn from being an avid reader of the forums.
In less than a year of membership here, I can say that through the forums and tinkering with my own system, I learned a ton of information that probably would have taken me several years of on the job experience to gather.
I spent a lot of time reading through "
view new posts", and looking at whatever topics interested me, then researching by using google and the forum search tool so that I could answer questions from others... They got answers, I learned something. For a broad sense of feeling like you know whats going on inside computers - I don't know if you can beat the experience you get from here.
I'm a senior in CIS at Kent State University, and I obtained a PC/LAN Analyst position at Sherwin-Williams HQ in April - If I said my college education was more useful to me than my forums experience, I would be lieing to you. As far as getting my job done, I learned 90% of what I knew coming in on the forums, and the forums were also a large part of my interview discussion. There are other aspects which have been refined in school as well as business coursework and writing though.
This might leave you with some gaps here and there, but the questions and problems run into on the forums reflect many common issues, and their solutions represent many useful practices and tools anyone who wants to work with computers should be familiar with. With enough individual effort and help from others, there is a ton to learn from this place. I keep coming back because I can see how much new members learn after being offered help from those of us who have been around this place for a while now.
