Call for Sharing (Google Reader)

There is a box in the right sidebars titled "Vine Ripe Tomatos" (My Shared Items) where you can see some of the article and sites I have found that interest me (I have moved this up temporarily so it is more obvious). I use this as a resource to help keep track of sources for topics I plan to write about.
Google Reader has a nice feature that allows sharing items and commenting on them. This allows sharing of things I find interesting with like-minded friends, and vice-versa. Potential, this allows me to see more of the thing I most like on the web, because people I know have already filtered and shared things they most like. It's really pretty cool, except for one serious drawback:

I need people to share with.

It turns out a lot of people I communicate with regularly don't use Reader, and I haven't made many converts yet. Therefore, this post is an open call for any people reading this to set up sharing between us.
I currently label (tag) items I intend to use on the blog with "DTA", which helps me but probably not anyone else. I will make an effort to use more, and more descriptive labels, in all of my shared items. Topics which I am most interested in reading are typically "Math, Science, Statistics". Items which combine science and humor are of particular interest.

If you use Reader, are willing to share, and have some common interests, contact me by the email in the right sidebar (or through my profile) so I can send you an invitation to my shared items.
