Like many others, I don’t think that RSS is dead. It’s my favorite way to keep up with highly valuable content on the Web. So I’m in the market for a replacement for Google Reader, along with millions of others. As I’ve evaluated options, I’ve had to eliminate some of them because I’m not sure they’re serious about what they’re doing. This post is about my thought process and why I think entrepreneurs should challenge themselves to get serious, and signal that intent, by not building free services.

I ran single-threaded performance tests to compare MySQL using releases 4.0.30, 5.0.85, 5.1.63 and 5.6.11. On my simple tests 4.0.30 is almost 1.5X faster than 5.6.11. I think it is important to reduce these regressions. Maybe this is an area in which the forks (MariaDB, Percona) will lead the way? I previously opened bug 68825 for this and will update it with the results I report here.
