It's still a work in progress, but since I've already inspired Hypocentre via Twitter, I thought I might as well make this more public:
View Geoblogosphere in a larger map
The idea is simple enough - a lot of geology blogging is about places - particular outcrops and formations - and I've long thought that giving people access to that information would be extremely useful. Not only does it provide more context when someone is initially reading a post, but it also gives people travelling somewhere new a heads-up on interesting geology to look out for when they get there (strangely, most guidebooks are rather silent on this very important question).
I've still got a fair number of back posts to work through, which will probably be added to the map in piecemeal fashion over the next few weeks, but there's enough points on there now to give you a flavour. Let me know what you think.
Ideally, I'd like to make this a group effort; I believe that with the whole geoblogosphere involved, we can sprinkle the entire globe with awesome geological content. Anyone who would like access to the map to add their posts, drop me an e-mail.

Very cool idea. I wonder, though, if it would be better to do some semantic geotag-y thing instead? Or post the KML in open text or .... ? I geotag my blog as a whole, but you could easily geotag each post and then they could be aggregated. That would be a lot more scalable.

That is the plan in the long run, but I decided that it would be good to have a starting point for any aggregation system.

This is cool, I'd like to participate ... I'll drop you a note in a few days

This is a super cool idea. I will send you links to the blog from our upcoming sampling trip to Mio-Pliocene marine rocks on Peru's desert Pacific coast. The map of South America is shockingly bare of blue flags.

That's a great idea. (I wonder if we could somehow combine forces with the IUGS's Outcropedia?)
