Tags are essential to all Web 2.0 website and from my experience folksonomy rules. They are really helpful when finding things, quickly, efficiently and to some extent in a fuzzy way.

I've observed two subtle but substantial deficiencies in the Ipernity tag system.

First, the tag system doesn't recognize word forms, so you best use singular and plural forms. For example if you are searching for a tag 'zeichnung' you miss docs tagged with 'zeichnungen' unless someone adds both tags.

Please compare

www.ipernity.com/search/doc?q=zeichnung

www.ipernity.com/search/doc?q=zeichnungen

Second, there seems to be a little bug somewhere that causes or caused some tags (audio files?) to be improperly trimmed.

For example

Please see:

www.ipernity.com/explore/keyword?p=all&s=audio

You'll notice odd tag pairs like 'classica' and 'classical', 'electroni' and 'electronic', 'hous' and 'house' and so on. Probably the bug is now gone because it is seen in audio files uploaded prior to July 11, 2007 (?) However it sometimes interferes with looking for some docs on Ipernity.

Wish - I don't know if this is at all doable but it might be nice to have a feature to help you with searching by tags - if you look for 'flower' to be offered also presentation of docs tagged with equivalent tags in other languages like 'Blume' and 'Fleur'. This way you could have included in your search docs tagged by German/French speaking Ipernity users.
