In Part Three, Trudy discusses a few more technical aspects of blogging. She touches upon "pinging", which is reminding the various blog sites that your blog has been updated. I know "pinging" is kind of a funny word, but then so is blog for that matter!
She also discusses RSS feeds for your blog. RSS feeds are simply an electronic announcement of when your blog has been updated. Your readers download a feature called an "aggregator" to collect the various updates.
