My take on the features (from what I have seen):
* Comment blocking probably a blanket service. So you can't block a particular person from commenting. And I can't just understand this concept of "only members comment" feature.
Rejoinder: Well, I muffed up the code on this one. I did not have all the lines of code that it required. Now it works perfect! And notice the nifty button that I have used to replace the script generated text link! I customised the button with this awesome interface to a cool button maker application!
* Titling of posts should be carefully done. Why can't just incl. another feature like "Page Title" or something that the user enters while posting (just like they incl. the title bar). That way user can decide how to name his pages and also do it in a concise manner.
