The first foc.us blog lived on tumblr. Tumblr was fun and posting was easy, but it didn't integrate too well with the focus store.
So we stopped using tumblr and switched to a magento blog extension. It was totally integrated with the store, but was horrible to use. Nobody liked writing in it, which is kinda the point of a blog.
So now we have moved to Wordpress. Hopefully this will give us an integrated fun to use blog platform enabling us to share more info about tDCS, EEG and the goings-on at foc.us towers.
