The
BlogAggregator mechanism has been developing over the past year or so in blogdom. Basically, you send an excerpt from a post on your own blog to a subject-specific aggregation site, through either filling out a form or using Trackback. A good example of this is the
[Blogs Against War] site. The
[Internet Topic Exchange] is another place where one can set up aggregation channels devopted to particular topics. This mechanism might be a good way to highlight interesting place-oriented posts on people's blogs, and allowing for greater awareness of these posts.
I just set up a
[Topic Exchange] channel for Place and Landscape and populated it with references to four posts. It is at
http://topicexchange.com/t/place_and_landscape/. To add to it, either send that URL a trackback ping or fill out the form at the bottom of the page. I already see one disadvantage to having a third party manage the aggregator: there's no way to edit content on that site once submitted. --Allan
