If there is any project I'd be tempted to be snarky about, it's PhpMyAdmin (although last time I used it, it was 2006). From an administration perspective, it was often a hassle, especially in its beginnings. It is a very successful tool and for a while had the same reputation as wordpress: being a pretty remote shell.
But what PhpMyAdmin illustrates very well is how important tools can be to environments/communities. For a while, the presence of PhpMyAdmin was what gave PHP an edge over many other environments: here's a tool that gives you (and tech-savvy people in your company) insight into your database, allows you to do changes and some bit of backup visually instead of fighting with the command line. And, if you develop on PHP, you don't even have to install anything additional on your platform. It made running PHP hosting without shell access feasable.
