Playing around with my Blogroll

I have started experimenting with Blogrolling. Looks like a very usefull tool for a blogger. One can easily add/edit links to other blogs and keep an eye on recently updated blogs. I will be playing around with my blogroll in the next few weeks so don't be surprised if there is massive disappearance/appearance of links in my blogroll. So far I have found about 60 blogs related to the Stock Market and/or the Biotech that I like. I will surely find more interesting blogs. One thing I am not sure is how many blogs are too many for a blogroll. Feel Free to Blogroll Me!
