Hi David,
I think that's a great idea and I also think that the infrastructure to properly support what you are talking about here is present in this forum.
Unfortunately, to be frank, we are have a few NLP trainers and their friends who frequent the site, creating dummy accounts and use them either to slag off their perceived competition or for other odd uses. They would, no doubt 'game' such a system.
So we would need to have a way of...
- Positively identifying users as being real people...
- ...and as being who they say that they are
- Insuring that the attended courses they claim to have attended....
...before allowing them to post ratings that would be meaningful.
I do encourage people to post reviews of courses or events, good, bad or indifferent. This has the benefit of being a little more difficult to fake as trainers and fellow attendees will tend to know who attended a training. It's also harder to review in any detail a course one has not actually attended without tripping one's self up. Not impossible, just difficult...
It also has the benefit of revealing a bit about the mindset and expectations of the reviewer which puts their opinions into, I think, useful perspective. Because, different people find different things more or less useful at different times and understanding where someone might be coming from might help one to know if it might be more or less useful for them.
Anyway, that's my thinking, for what it's worth. Any other ideas?
Be Well,
Michael Perez
