Dataset - social tagging

Hello ! I need big data set from social tagging Web 2.0 service like [login to view URL], flickr, technorati or other similar, where users enter own tags for resources i.e. articles or blogs. I need to test some tag clouds generation algorithm testing. It should have informations: - date (if possible) - resource url (article or blog) - user id - user tags for resource You can search for this type of datasets online. If you have link to free online datasets of this type i can pay you too. Please deliver sample - 50 records if you have something of this type. Big for me is in example: 200k documents (resources, links), 30k users, 30k tags, can be some bigger can be some smaller. I need something quickly, no need for data retrieval, better is ready set.
