Sqlite is fine for small scale systems. It is not a "web scale" database, but not every web site is "web scale." SQLite does have performance limits, and will break at certain load, but until that, it's okay. For single user databases, like desktop applications, SQLite is awesome! What the others bring to the table is concurrent sever performanc, user management, and such. There's nothing surprising about this, right?
