David Farmer asked me to investigate ways of alerting regular readers of this blog to new posts and new comments on existing posts.
One solution is RSS feeds (though still somewhat passive). I added a "Subscribe to" widget to the main page (upper right-ish) that allows people to subscribe to RSS feeds for new posts and new comments. All of the popular web browsers support RSS feeds, though in different ways.
I also added a "Follow by email" widget to the main page. Adding your email address to this will cause you to be notified once a day, by email, of new posts (not new comments).
I'd be interested in ideas from people on alternative solutions to the notification problem. Tools that integrate with the blogger/blogspot platform would be best, but I suppose I'm open to moving the blog to an entirely different blogging platform if it's warranted.
