Ive updated the script again, this time i added "Recent photos featuring this user" and "Interesting photos featuring this user" filters. These do a search for the following tags: "me,selfportrait,flickr:user=username" on the users photostream, and return either the most recent or most interesting matching photos depending on the filter you choose.
Added recent+interesting "Photos tagged with..." filters, which works similar to the previous addition, except with this one you can choose the tag/s you want to search for.
I also fixed the "testimonials they wrote" filter and the intermittent stream duplication bugs.
All my flickr greasemonkey scripts can be obtained here and they are mirrored here
