As a self-professed web geek, I love this and is not, in fact, very difficult. An example with del.icio.us would be that the address for my forums is http://del.icio.us/basswulf/forums: by appending “+quicklink”, I can filter that down to all the entries that have both links (ie. the set of forums I like to access on a regular basis). Therefore, it gives me the ability to interact with my information in a very flexible manner.
Although Flickr also has some options for URL manipulation, this technique regrettably doesn’t work. If I wanted to find all the pictures of me playing with The Elusive Teeth I thought I either had to type a much less obvious URL or use the search tools on the page with all the attendant delay and extra clicking.
Therefore, I was pleased to discover a little publicised feature on the site yesterday: separate the tags by commas and the magic works. For example: http://www.flickr.com/photos/wulf/tags/elusiveteeth,wulf brings up all my recent rock star pictures!
If it is useful to me, it may be useful to some one else. The presentation of the resulting pages is a little quirky and I hope that one day Flickr might standardise one the same “+” formula that del.icio.us uses but, for now, I am happy with my new trick.
