I have to agree. Guilds have limited space to write stuff and cost money to maintain. They're also easily destroyed and require active characters to keep them functioning. The administrative overhead and risk of destruction don't make it worth it IMO.
The only thing you could really use one for is as a library perhaps by having the internal description include a list of links to books/pages on the wiki - but I'm not even sure if direct links work if they're put in a description.
I think people make too many special-purpose guilds. Guilds with special purposes often lose their purpose, and then there's little reason to keep it around other than nostalgia. I think people should focus on combining the purposes of compatible guilds rather than having to build a network/infrastructure/membership for each and every one.
