Drupal and the perception of success
This is the result of seeing one too many 'For Drupal to really succeed' posts. Drupal is already a success. There is certainly room to get better and grow more, but Drupal has already succeeded.
When listening to interviews with musicians who have a new 'hit' album/song I often get a sense that the interviewer has this fundamental assumption that the artist just started playing/singing last month. When you listen carefully, you find that the artist has been working at their craft for years. So it goes with Drupal and Drupal's success.
For the time I have been with the Drupal community we have had a steady progression of success. In my first few years, the community took pride in the fact that sites could be built by skilled developers with no indication that it was using Drupal (Yes, many hobbyists often implemented sites that were obviously Drupal). Calls to put 'tagging' into the code to more easily identify Drupal based sites were often met with resistance. The prevailing attitude was to focus on quality and capability rather then count implementations.
