Fame and glory
Imagine, if you will, a small-time author. This author hasn’t had any kind of publishing deals, and writes more or less to amuse himself.
Now imagine that Stephen King (or Terry Pratchett, J.K. Rowling, or whoever your favourite author of the moment happens to be) publicly reveals that, not only has he read your stuff, but offers it up for others to read too.
Matt Mullenweg just linked to my blog. This is a Good Thing™.
(Addendum: for the lazy, a link to the article in question.)
LOL, now watch how your stats go through the roof 😉 Every time Si or other more famous bloggers link to something on my blog, I get about a 20% increase in unique visitors for the month!
