Libraries and archives
After many years of self-employment, I took a steady job (aged 51) with my local library, and quickly became their computer support, for rolling out 'Internet for the public'. As part of that job, I promoted the idea of blogs, Twitter, Facebook, etc for the library itself.
The were slow to adopt the idea, so I put up Anon the Librarian's Unattributed Ideas, as a sampler blog.
After I left the library service, my old circus chums hired me to build an archive of their 30 years' history (see vid below)
