I'm a VERY happy user of WordPress and I happen to discover today a CMS-Matrix of pretty much every CMS available, allowing us to compare the features of the various CMS between each other.
Sounds very usefull.
But I also discovered that WordPress features and latest version listed was 1.5 only.
There have been MANY changes since and the most obvious ones being not listed, I felt bad for our community of developers who wasn't given a proper advertisment for their efforts.
Being not the most educated on the subject, I suggest some developer(s) send them an email to adjust the data listed regarding WordPress.
Cheers and keep on going your tremendous and very appreciated efforts :)
