I just added two new methods of subscribing to this site via email. I've replaced the Bloglet sign-up form (in the side column) with one from FeedBlitz. (For those of you using Bloglet, yes, that service will continue to work. So if you're happy with Bloglet you don't have to change.) FeedBlitz, like Bloglet will, at most, send one message per day with a summary of any new content here.
The other method is using RssFwd. RssFwd will send one email per new entry. You should get a message within an hour of any new posts that I make.
Note that just like with a RSS newsreader, you can subscribe to any RSS feed with these services. So you can get updates from your favorite sites pushed to you (assuming they provide a feed) instead of having to visit those sites to find new content.
P.S. I've had a couple of people tell me that they've miss some of my new posts or don't see some of the links before they roll off the front page. The best way to keep up on everything is to subscribe via the RSS feeds (or email). Those of you subscribing to the links feed via your "My Yahoo" page may want to increase the number of articles/links it displays to make sure you don't miss anything.
Thanks for the advice on the RSS feeds.
