Use UTW for links to your own tag space rather than technorati
Add nofollow to the bookmarking buttons created with Sociable
I have written in the past about how a blogroll can kill your pagerank, this is a prime example, especially for a site that has so few incoming links. The blogroll is currently site wide, even on pages that are duplicate content - it is suicidal
Here is an example post
http://www.digitalphocus.com/2007/03/04/ipo-chatter-a-tad-excessive/Pete Cashmore has a post about Bebo... why didn't you link to the post itself? Trackbacks bring in traffic, and encourage others to link to you...
Links - so few links even in Yahoo which shows nofollow links
Where are the page views coming from? The Alexa rating is so low compared to the page views, it doesn't seem genuine. Sitemeter reveals all - how can something have 859 views when you have only had 100 visitors since it was written?
The alternate ads you are serving when no Google Adsense are available overlap the right hand margin.
This might be slightly underhand, but write a post about different type of metrics, such as Alexa, and Compete - link through to the Search Status plugin for Firefox as well.
You might think Alexa is unimportant, but it is often used as part of monetization calculations.
You need to widen your sources - you have only have links from 23 blogs in the last 6 months - also comment on blogs that have top 10 commenters or dofollow, and remember to ping technorati when visiting occasionally

Think logically - would you put someone elses widget feed on your blog? No? If you are not someone like Techcrunch, no one is going to do it
MBL - I would keep it for social proof and actually use the service to go looking for other blogs in your niche, join the blogs of your members and interact with them.
