Gennady Feldman has posted two comments/suggestions about things he thinks could be done to improve the PEAR and PECL websites:

So I attended the PEAR2 presentation and had a chance to bug the guys behind PEAR/PECL. There's definitely exciting stuff happening and they are pushing forward with many exciting ideas.

His suggestions include updates to documentation, crrection broken parts of the API and a "Package News" feature with the ability to leave comments on them.

He's also posted another suggestion - the ability of the authors of the project to provide other links besides the ones just for the project (external documentation, tutorials, etc)
