Nicolas Kayser-Bril, contributor to the Online Journalism Blog and Observatoire des Media, has created an index of the interactive tools used by European news websites.

The index compares and contrasts which media organisations make use of tools such as Twitter, mobile alerts and social networks, as well as noting their policy on user registration for interactive services.

News sites from the UK and France, to Macedonia and Hungary are featured – entries for additional organisations should be submitted to nicolas@observatoiredesmedias.com.

Below is the index’s comparison of interactive features used by Sky’s site vs Guardian.co.uk:

The project is an extension of the work by Birmingham Post reporter and blogger Joanna Geary, who looked at the use of interactive tools by business news sites.
