...https://bugs.maemo.org/show_bug.cgi?id=6533 needs to be resolved as INVALID (as Andre points out, one issue per issue); new enhancement requests for each service need to be created (and ideally a comment added to #6533 pointing people at the correct issues for each network)...
When raising an enhancement for a social network to be added, the following info would be useful to include: Generic or friends oriented? i.e. is it a service which will provide information for anyone (such as Gravatar) or one where you have your own friends (LinkedIn, Facebook, Twitter) Fields supported: what fields from this service would be useful (assuming the API exposes them) Identifier: the main identifier which'd link a user in the address book to a profile on this service.
What anyone else said about MySpace isn't important; however if you can provide as much of the above information as possible in a new Bugzilla entry, it's more likely to be done
