Joost clearly feels bad about the release bugs, and communication issues. My company manages hundreds of sites, and probably a third of them use YOAST SEO. And about 50% of those use premium adds.

Joost would be the first to tell you I don't pull punches, no matter who is involved. And I would still recommend his plugin over AIO hands down. Why? Because it's a much better plugin for one. And two, Joost would never try and take advantage from another's misfortune. The fact that AIO did here is reason enough not to trust that author.

Did 3.0 cause problem?. Yes. Is it reason enough to abandon the plugin? Not in my opinion. But to each his own. Joost should be commended. Not just for the plugin but for the tons of work he's done to educate users about SEO.

Want to make sure plugins won't cause problems during updates? Use a staging site to test changes and back your sites up before committing those changes to your live site(s).

The last thing a plugin author wants is a buggy release, paid or not.

Lastly, if you get paid to manage client sites like mine does, you should take the precautions I just mentioned. If not, don't come crying when it occasionally goes bad, because it's software and it's gonna happen.

Joost, still love your work. Still hate the post update nag messages ;-)
