Respect MJ, deep respect for the selfless cause you have committed yourself to.
I have reviewed hundreds of blogs here and outside the Indiblogger space, but haven't yet seen something quite like your venture.
Here goes my review.
1. The blog is is neat but it lacks croudpulling widgets. From the cause you are fighting for, I think you need better traffic and reader count. Start a facebook page, and add a widget here with a like button to it. Try all such gimmics to get traffic in there.
2. You can add a labels section, an email subsciption widget and the like.
3. You could make your blog more colourful [Let the people see for themselves what the blind folk are robbed of.]
4. As far as the writings are concerned, you could make it a bit more touching. As I alread said, respect the cause you are fighting for.
