There was talk long ago about linking all of the sites together. Back when the admins of each site talked. It was decided back in the day that the three major sites .org (Development and Documentation), .com (News and Modules) and .net (Themes and Screenshots) would handle a specific piece of the puzzle. This was all well and good until .org didn't get renewed and .com disappeared off the face of the planet. Honestly I couldn't even tell you who runs the other sites anymore. The "merger" isn't as easy as it sounds and would basically turn it into one big site spread over three domains on hopefully different boxes and pipes. You would have to convince all but one of us to give up everything we have worked on to mold into another site. Personally I like having the different perspectives on the scene as is. The TLD's should do everything and leave sites like LS-Dev for their specializing.
