That is probably the best discourse I have seen on delving into Linux. Have you considered turning that into a document and posting it in the Linux discussion area?
I attempted to shorten the learning curve by purchasing the book with all the disks, but the book really didn't delve too much into explanations or teaching the differences. It probably didn't help that it was version 7.04 v 7.10.
One warning I would give in looking for help on the Linux forums and user groups (Usenet) is that there seems to be several different types of people who seem to be willing to "help". There are those who are basically anti-social geeks who know it all are superior to you, and they want to let you and the rest of the community know it also. Sad to say you just have to put up with these people and learn to ignore them. They usually do not offer any real or significant help, just insults. There are the basic geeks who think you are just as knowledgeable as they are so they tend to use acronyms and basically their help sounds like Greek. They are well intentioned but really don't know how to pass their knowledge on to you, you may get a tidbit from them that might be helpful. Then there are the users who are both knowledgeable and recognize that they too were in the same boat you are in. They will provide the most help to you. Just be patient and wade through the rif and raf and chatter, you will get there.
I don't think the Linux users have a monopoly here. Many "help" sites in Windows suscribe to that model as well. I think that one of the things about the PC World site that makes it so great is that most of us take the latter attitude. As mph is fond of saying - we were all newbies once.
I guess one thing that has helped in this regard is that for years my late sister would call for help. Stepping back and explaining to her over the telephone (she lived 750 miles away), helped me in answering questions here, but it is much more difficult, you don't know how much they know and you have to wait for a written response.
The mistake I may have made is instead of going to the Linux thread here, I went to the Linux forum, and like others starting out, probably got ignored. I note also that there are a lot of Mac postings on this community instead of their own site. Maybe they feel more comfortable over here, and I know we have several who delve into Mac's as well as Windows machines. After all they are all - personal computers.
