Today I finished with adding new features to this blog. The most important feature is the possibility that you can add comments on the posts, without registering to the blog. I choose Cryptographp plugin, and I am satisfied with it, for now.
Several weeks ago I add PostRatings plugin, you may noticed it at the end of the posts. It is interesting Ajax functionality.
I replaced WP-Notable plugin for the submission to social network services, with ShareThis plugin. It uses less space, it has good Ajax functionality, and adds email posting.
I also added Related Post plugin, which has the similar functionality as previous Terms2Tags plugin. In addition, I enabled recent posts to be seen on all blog pages.
I hope that mentioned changes will results with better blog experience.
