When I first started using Tweetmeme on my own personal site, I ended up blogging on how it was not validating. In fact, Mike Little pointed that out too when visiting the site. Tweetmeme plugin developers eventually validated another earlier version that I reported (and I am sure others did too), but somewhere alone the line, that got lost.

As few days ago I had to take down the plugin for the Tweetmeme retweet button because of this issue and reported it. I received an email this morning from Tweetmeme that they have corrected the URL outputs and validation, as noted in the Tweetmeme button changelog.

I have since upgraded and activated the plugin. Version 1.7.2 of the Tweetmeme button is confirmed as validated! So for those code ninjas and W3 accessibility folks, it is good to use.

I also suggested to Tweetmeme for future versions to add a function like the Sociable plugin for users to be able to disable the button on individual pages or posts as obviously some pages might not have any valuable information to retweet (like contact forms).
