I once found a poem about sunflowers which explained it all. Blogs are like sunflowers in a way.

I see you there in glory shining bright,
Following the sun and its path of light.
Standing tall above all others in the field,
You grow, conquer, and do not yield.

I can learn from you, my friend.

I keep my blogs (I have few I confess) up to date because I constatly learn from others on the web, and I feel I need to give back.
