I understand exactly what you mean Alan and as a site manager over the past 6 years, I have seen many of such examples.
The good thing about posting is the help some people get from others who are more experienced. For the more experienced, I think its more a case of social interaction and a bit of fun more so than expecting a pat on the back.
I personally like the video postings that carry a bit of humour. They do get a lot more responses but also take a great deal of time organising....just ask me
Anyway its always good to hear your comments as you have a lot of experience and general knowledge. I used to like all those old Shads videos you used to post...they were great!!
Maybe you could again pop in the odd one here and there

Cheers
