Over time you'll notice that some people are unfriendly towards linux newbies.
I recently dove into Linux headfirst. I've only run into one person that was rude. That person was relatively new to this forum, but apparently not to Linux. I bit my tongue and moved on. In cases like this and to prevent some personal resentments, I have to assume it's nothing personal and they're just in a bad mood.
The biggest difference I've noticed between this forum and Windows forums is that the people here are so friendly. They don't seem to take life too damn seriously and are more than happy to help.
I've never felt very welcome at any Windows forum. They always seemed to assume I have an empty head. I've been tweaking PC software, repairing software issues, fixing hardware, upgrading hardware and software for a long time. I built my last computer. You'd think that would have come through in the way I talked about things, but I guess it didn't. Sometimes I may not have used the correct term for something. You'd think they would give me a break on that one. Despite all my efforts I was still blown off.
The last time I was at a Windows forum I was having some trouble figuring out exactly where to plug in the power switch I was replacing. The replacement plug looked different. I posted pictures of my MOBO, the model number circled in red. A pic of the new plug, the old plug and the place it was plugged in, the specs to my MOBO and a link to the manual for my MOBO. I gave them everything I could think of to make it as easy as possible to help me using words that hopefully would indicate I have some amount of intelligence, knowledge and that I'd tried to figure this out before asking for help.
The very first reply I got was the very same link I gave them to my MOBO's manual. Thank was it. I got some answers that I know weren't correct and some erroneous assumptions before someone finally looked at the info I posted and gave me the simple answer I needed. I was lucky to get an answer that time. I usually end up finding my answer on my own.
The only thing I could say about being in the right place is that I was advised to go to the distribution specif forums. But again, no one seems to hold it against me if I post in the wrong place. They just move it and tell me why in a very friendly way.
