but I suspect, after the first 3 categories, that we are not going to be able to agree on a subset of WHS which could, on some set of objective critera, be described as " best", "most important" or similar!
I disagree. I think it is worthwhile to establish such a list through discussion, but this will take some time. At the end we could vote for each category where no consensus is reached.
I agree with Assif. I'm very much looking forward to dive deeper into e.g. Glaciation sites (which I must confess I never cared about so far), but it takes time (and my holidays are just over - sigh). This has only been up for 1-2 days, so it's too early to judge.
(BTW: Thx for reviving this initiative, Els!)
