Let us not get into a slagging war. No need for that at all.
I think DenhamPPL is perhaps just trying to advance an aviation view of spotters. After all, we were all spotters once and will stay one I expect.
For sure, those celebs who hold a PPL or an ATPL will not be able to to keep their eyes on the ground if there is an aircraft in the air so I suppose they can be called spotters - each of whom fits in at various levels from the idle once in while spot to the aviation geek.
However, make a post if you wish but if we see any that are in attack mode they will be removed.
Perhaps PPRuNe will also get a mention as almost certainly the world's best aviation site.
