1. Buttons which do nothing ("expand to show further panels...").
2. The question marks after "Change Location, etc" are really sized badly.
3. You are displaying escaped HTML in the right most scroll ('<b>Obama</b> says that...').
4. You inlined all the scripts AND stylings.
5. Design is very busy and doesn't look professional. In particular the 'WebLivz' box in the top left doesn't match theme and clips over existing text.
6. 'Please get involved' text isn't centered.
In summary, the site feels thrown together and adhoc. There are little problems, and bigger ones. I don't think this has enough polish or focus to be released for public consumption.
You need to a) simplify the design, and b) explain your added value to users, because it isn't clear how this is going to replace my RSS feeds.
Sorry to be critical of your work, but it really needs more polish before you start asking for public feedback.
