I'm sure there are things you want to discuss that might be well beyond the average amateurs understanding, but keen diyers still want to hear what interests the pros. It's a good way to learn, if you don't mind us listening in....
Your technitalk also shows us clearly what we don't know and when we are well out of our depth. Which has to be a good thing. Anyway, for all we know, you're having these secret sessions already.
The fact that diynot swamps the google ratings is down to good marketing - you shouldn't really complain about it.
Frankly I'd be worried that you want to have private discussions anyway. Is it because you think you're giving away all your knowledge for free, or is it because there's lots of things you don't actually know, and you don't want us to find out?
Of course, a downside could be that you attract the REAL pros, who put you in your place, and you wouldn't want that would you?
This is a great forum, please stay. Can't you persuade the fat cat to reward you? Oh no, more regs.....
