Over the last few days, I’ve attempted to solve a bug relating to WordPress’ behavior of pinging the PRC services even on drafts and edits. There is a plug-in for resolving this. But, if the user doesn’t have this plug-in, the result is multiple entries of the same thing on the Updated Blogs section of the new Weblogs.us site.
However, if the article URI is the same as some previous URI in the database the ping can be ignored (no need to go out and fetch the RSS feed). Now that this works, I will test a few refinements, which will result in a slightly heavier load (possibly neutralized by sending less data) for the database server, to reduce the load greatly on the Apache/PHP server. After this optimization, I will continue writing the code for the listings system.
