I am the Walker . com
I subscribe to the mailing list of the Walking Artists Network, a group of people who write, mostly, about walking, mostly.
One of the members collected a list of all the websites maintained by the group’s participants, which I figured made sense to throw into an RSS aggregator. Turns out the group is quite prolific.
The website of course has an aggregated RSS feed, though you can subscribe through Twitter and Facebook as well.
In November 2019, I am the Walker . com was moved into walk · listen · create, adding a range of functionalities as well as becoming the home of Sound Walk September.
