Some of our long time readers may remember last April when we wrote a post about Technorati wanting you to upgrade your WordPress installation. In that post, we explained that Technorati will no longer be indexing your site if you have an old installation of WordPress running on your blog. This is of course due to the major security vulnerabilities on some old WordPress installations. Unfortunately this announcement didn’t get much attention, as Technorati has failed to grow with the blogging community and has basically become irrelevant over the past year.
With that said, for those of you on old WordPress installations, maybe this will be a bigger incentive to upgrade? According to Quick Online Tips, it looks like Google has begun warning users of WordPress 2.1.1 via their Google Webmaster Tools of the security vulnerability of this version. If this is successful, Google will then expand to notifying webmasters of other vulnerable WordPress installations, as well as other blogging platforms. Note: This does not affect WordPress.com users, as your sites are automatically upgraded for you.
Why is this important? I believe that it is conceivable that eventually Google could not index your sites that are using a version of WordPress that are considered unsafe. This is because these blogs are targeted by hackers and inappropriate content or malicious code is often placed on these sites. Google does not want these types of sites in their index.
I know there are a few of you out there that don’t necessarily upgrade your WordPress installations. Will WordPress 2.7′s easy upgrade process help you to upgrade your installations regularly?
