This is one people have asked about a lot.   We just pushed out a new publisher today for Flickr.

The new Flickr Publisher supports the Gnip TAG rule-type and allows people to easily integrate data from the Flickr API using the Gnip platform.     In the near future we plan to add support for the Gnip ACTOR rule-type, so stay tuned.   In the mean time it is very easy to define the tags that match your interests.  Not sure what tags to use, just check out some of the most popular tags being used on Flickr.

Check it out on http://api.gnip.com and go use Gnip to integrate some data from Flickr!
