Would be great to see Odnoklassniki.ru and Mail.ru added to the Russian services. Specially because it looks like there is issue adding Odnoklassniki.ru via custom service (http://drupal.org/node/1861982).
Here is the page reference: http://api.mail.ru/sites/plugins/share/
Thanks for the module.
For the first follow the discussion you linked, the second (which is a widget including both, as far i got) needs more work.
