I don't really see it as my mission to spread the word about independent music. I simply often don't enjoy what I hear on the radio, and I know there is so much good much music which gets so little attention. At least now quite some listeners who are into discovering new music, discover these artists via TalentCast.
The problem with the search engines is that the website constantly gets a so called algorithm penalty. For example: After quite some tests I discovered that I cannot have the Song of the Week text about the artist on the main page and on the playlist of this week. I now permanently removed the text from the main page, only for that reason, not because I want to. I changed much more, and I hope to see the results of that in a few weeks. When the penalty is gone, the website will for sure perform better with key words which are important for our project.
I know that you also you ask permission to the artists for your radio show, but I still prefer my system. When artists join and use the upload page to send music, I can prove they really want their music to be broadcast and podcast, and I have all administration on one place.
When I read your story about your health, I can't complain about mine. There is also much more than just my low vision, but at least I am still so lucky that I can still freely move around, without being connected to a machine. That's quite something, I realise.
