I recently finished a medium to large sized project, that I would not have been able to develop were it not for wordpress. I created an intranet that has an employee database using custom post types, that I plan to turn into a plugin, as well as a document directory with uploads etc. Everything is searchable using wordpress search functions. WordPress and its open developer community has been extremely helpful in assisting me "conceptually" as a developer. I just want to say to all the wordpress developers and the community as a whole thank you. I make my living from wordpress!
