Also, just to note, there is some caching and secondary systems where all the data is not current.
Example. We are working on a new Article System where the articles are being copied to a second database. This second database will be smaller and faster than our Primary database, which holds everything. Not all systems are using this new article database yet. The forums are using it, but the main JoeUser site is not yet. So there is delay time for an article to show up on the forums. When posting an article to your blog it gets written to our primary database. We have a job scheduled to sync the new/updated articles to our new article database system which runs once every thirty minutes. So this could be part of the issue.
Also, the forum code caches much of its data so some things may not update right away. Cached data usually refreshes itself every 1-3 minutes.
So these could be some reasons for the inconsistant data that you are seeing (or not seeing). We still have much to do and we will get there!
