I had to quite fast update both fzTagPlugin and sfForkedDoctrineApply, and since Me and several other users discovered some bugs just after I thought it's all fixed, both plugins had several releases. Crazy sunday as it might seem.
For fzTagPlugin, it looks like I forgot to apply the limit to tag cloud query after randomizing it and yet. So in fact tag cloud became tag fog, or tag storm. This has been fixed for fzTagPlugin 1.2.3, unfortunately, had to actually use two queries, to get most used tags in random order, since it was quite impossible to useLIMIT in subquery. You can see the outcome, using tagCanvas component at the bottom of my menu column.
For sfForkedDoctrineApplyPlugin,there were some painful leftovers from dumping Profile's email field. Should be fixed in sfForkedDoctrineApplyPlugin 1.5.4. Next step here should be OpenID and Facebook login integration.
