Personally I enjoyed the most the article about Einstein. It’s a great idea to have a blog and to give us so interesting infos. Maybe you could tell not only about great well-known people (though I like it too), but also about our contemporaries so that we know them.
It would also be great to invite some violin players (famous if there is a chance. I know it may be hard to find those who wish to do it) so that he/she tells some ‘little secret’, it may encourage beginners and intermediate players as well.
