Are you a good writer? Do you have a few minutes to spare? Why not update some tags and get the tag editor badge!
See any synonyms you could suggest? Consider it.
We have a lot of tags that are quite detailed, while others, eg cambodia had a one line 'it's a country in SE asia' style tag. We could be adding in details, maps and more.
'things to do outside' for [tag:outdoor activities] is another one that could be improved.
I could edit them, and have done so for many, but if you've not gotten your badge (only
90 143 have!) maybe it's time to go for it, and we can all benefit as a result :)
