GEOLOGY can be intriguing when much of it is set outdoors (in videos, no bug bites, no poison ivy) and being explained by a professor at a small college with a great love of the topic and a talent and desire to share it with a large audience. Yes, I’m talking Nick on the Rocks himself. Danger:He’s often accompanied by other interesting geologists. It might be catching.

If you’re new to the topic or have children, then Nick also does short (under 10-minute) shows that are shown on PBS, which you’ll find here:

Oh, I’m thinking about 20 minutes in line outside a small community center, back when I lived in North Dakota (pop of whole state about 600,000). As a lifelong nomad, it was the only state I lived where I actually attended a Democratic party caucus. It was an enjoyable excursion into a behind-the-scenes election process that most will never venture into. Best part was, I escaped without being signed up for anything more!

Some way of grouping Communities other than by name (not very useful). E.G. search on ‘Climate’ and you don’t get the name of one of the busiest communities.

In other words, group them a step up the taxonomy. Create 10 or 15 groups (sci/tech, history, music, culture, media, nature, issues, locations…), see what mods have to say about that list. (Could do worse than the Wikipedia taxonomy.)

Have a look at Gorbachev. A big loss, that.

It can be hard to find the right community to post a link in. Figuring out the rules and knowing who’s reading them (and sometimes what they’re really about) might cause someone to give up. (Especially when people complain about ‘this isn’t the place for that’ without stating the better alternative.)

For Krogh, the source of the number, it was a quite reasonable estimate, which was about all that was possible at the time. And it was ‘wrong’ by less than an order of magnitude … compared to the newest estimate. AND an estimate of a truly unimportant number is as good as you can get (or need) in many cases. What’s the total length of all the ice cores drilled since Camp Century? And their total volume is?

Either greed or religion has killed the most people before their time. One of them has to go.
