I just noticed gchange has hashtags. That is, if you put a ‹ # › and a word you can tag an ad and find other ads with the same tag. (Even if you’re unaware of hashtags and their purpose, for example, if many users add the tag ‹ #horror › to their books or films, everyone who is looking for the horror genre can find their advertisements.)
I don’t know if tag wrangling is implemented (a feature that equates ‹ #english › with ‹ #anglais ›, or synonyms, etc). But I think gchange can be an extremely powerful listing site compared to standard solutions.
However, there doesn’t seem to be an index of tags, and not everyone is using tags in their ads. I think the following tags could be useful:
- for used items (e.g finished reading a book and don’t need it around)
- for produced or created items (e.g homebrewing, raising a plant, or original project)
- (the offer is in) a certain language or targeted towards speakers of that language
- genre
- free culture
If you use tags on gchange, what are you tagging?
Some examples:
#english - https://www.gchange.fr/#/app/market/lg?hash=english
#freeculture - https://www.gchange.fr/#/app/market/lg?hash=freeculture
