Dr Hipp; If you're doing a PR stunt, you should take a lot of these emails and put them on a "What users say" page and link them to the email thread (If it is accessible by the public -- I get this list in my email). That way you'd get real comments about the stability of SQLite against real world applications.
Myself, I'm a lowly desktop developer who writes stuff for my own personal use, and have never distributed anything with SQLite to the public. I have distributed a program within my place of employment that handles an infinite number of alarm clocks though....
