Five years ago I published my first article about SQL Server, "Index Covering Boosts SQL Server Query Performance"
It is still quite popular - I just googled up "index covering", and it comes right on top.
Bing does the same thing. It was just mentioned on stackoverflow, this is how I realized it was that long ago.
Since then, it was all downhill. I wrote a lot of articles, dozens of blog posts, and a book, I liked the process of writing a lot, but they are all less popular than that first one.
Anyway, thank you, my readers! Special thanks to those who share their feedback, leave their comments!
