Too bad you have been frustrated with this. It can seem like a waste of time when you just need the information. I've been on other discussion forums (I don't chat) and I've seen snarky on all of them. sometimes people can actually be trying to inject humor into their posts, or being sarcastic, but it might be taken wrong by another... before you know it you are totally off the original topic, or its obscured by egotistical comments, someone taking offense rather than sticking to the topic (I'm sure this happens less here than, say, a family-oriented site where there is emotional stuff involved).
I've read several posts, and happened to read the Behr paint thread mentioned,just a little while ago.
As far as one pp said regarding "experience" being a factor ---this will vary between individuals, depending on how you learn(some people need tactile, hands-on, some people are visual, needing pics, some people can do great with text, diagrams). Someone who knows you well, may be the better teacher than a bunch of strangers, as they will use familiar terms, language you can understand, and will more easily understand your responses...
Some people can do a perfect, professional-quality job IF they have detailed instructions (covering ALL variable factors; not likely to be covered in most discussion threads), AND if their reading comprehension is good. And if they have time. No way will you do as good a job in close to the same time as a pro. But a great job can be done with care and attention to detail. My reasons for wanting to do things myself are that I do have the time, I don't have the money to pay someone else to do everything, AND there are things I know I will be happy to learn no matter how frustrating. Some terminology may be foreign, so time would be required to find definitions and explanations for things.
Regarding the exhanges on the other painting thread previously mentioned...I totally "got" what the guy was saying about Behr being OK....he wanted to contribute to the discussion. Although pp made a good point that those who have worked with a particular product would be better to give advice...here on the forum, who knows who has which type of experience if the poster does not share that information? AND SO....your average joe, such as myself, and the other guy who was OK with the Behr, might think he's just as qualified as the other guys. I have to admit I'm not even going to try to give anybody advice. I came here to learn...maybe I'll be able to post some pictures someday.
Perhaps when posting, you guys with tons of experience, professional or personal, might want to share your "qualifications" at the beginning of your post; maybe even put it in your signature, if you have a particular knack, passion or expertise for something. That might not discourage others from posting, especially if they think they also have lots of knowledge to share. But perhaps would keep minimally-experienced posters from commenting, dragging the discussion into snarky territory.
God only knows why anybody would think 6 coats of paint is OK to cover. In my inexperience I would probably take it back after 2 or 3 coats, to the store and tell them there's something wrong with the paint. LOL. The guy who posted that said that he was no expert, did not try to convince anybody of anything, nor did he try to speculate.
But that goes to show you, the guy had good intentions....also, people naively assume since a product has been around, is sold in major retailers, that it must have some redeeming qualities. Someone thought that the Behr paint does...many thought not; and thankfully this forum is here to share all this valuable information. The guy innocently posted comments and got some flack...which is what this thread was started for. It happens that sometimes people misunderstand. some people crack jokes at someone else's expense. some people criticize a product or technique when others on the same thread have nothing bad to say about anything...different strokes for different folks.....
My first and only original thread I wasn't sure what kind of response I would get. I'm a total newbie, to everything. I thought I would get insults or nothing. My post was greeted with encouragement, making me want to come back. I'm sure that was lucky; I could have unluckily been met with some snarky, discouraging comments making me want to fork over the money to a contractor.
Though I haven't personally posted much here (I really haven't got much to share), what I have read is the reason I come back. Lots of KUDOS, shared information, pictures, insightful tips. All kinds of personalities here, but overall its worth wading through the waste, in my opinion.
