Mr. Nice Ash will be missing a lot of his favorite blogs since their corporate network will be installing WebSense. WebSense is a blocking software program aimed mainly at the corporate market but also used in some schools.
An alternative to subscribing and reading blogs is via email and FeedBlitz does this quite well (and I believe to be the most widely used service for this specific purpose):
FeedBlitz reads your blog’s RSS feed – a computer-readable form of your blog produced by all the blogging tools out there. It then figures out what’s new and sends the updates to subscribers by email.
The free standard service (nightly updates, no user-based branding or custom graphics) is FREE for publishers and subscribers. There are no ads, no popups; just your content formatted and delivered by mail.
With this, you can have a subscription form available on your blog where readers can sign-up and get updates via email (see the right nav box). There’s also a running count of subscribers just like the FeedBurner chicklet.
