What geocahing is and the controversy that surrounds it.

…that the sites’ creator, Jeremy Irish, tried to trademark the word “geocaching”? He did so when the word had already been used for months as the common term for the hobby, and failed.

…that Groundspeak Inc, then Grounded Inc, wanted to file a lawsuit against Navicache.com for the use of the word “geocaching”? This too failed, and Navicache responded by increasing their site activities and making it a full-fledges site for geocache listings.

…that banner ads, merchandise sales and paid memberships were used to fund geocaching.com? This despite many attempts to keep geocaching non-commercial.

…that geocaching.com used to censor the names of other geocaching websites? People were not allowed to utter them or link to them on geocaching.com.

…that the site tried to merge the much older hobby of letterboxing with geocaching, which was resisted by many members.
