I felt pleased to see that Socitm decided to encourage the use of 'social networking' in businesses and organisations, rather than block staff from using these tools, and learning how to work them.
As an early-uptaker, it seems to me that blocking staff access to modern tools seems like refusing to let them use a phone, because they might spend time gossiping, or arranging their evening drinks... Apart from the patronising attitude (and lack of trust) to make phones completely unavailable as a 'solution to the problem' would render most library work virtually impossible.
So, the council now trendily uses Twitter to contact its customers, but prevents us workers from using it at all; the public can use Facebook, but staff are discouraged from using it during work time, etc.
I know we only have to patiently wait for the inevitable, but I have an impatient temperament.
Look at Manchester Libraries, with their Facebook Page, their Twitter connection and a blog - The Manchester Lit List.
