You keep asking how they [autograph pages] help build an encyclopedia. But you also link to WP:EA. I think that is your answer, no? Anything that builds a spirit of friendliness and co-operation and helps people get to know each other as human beings seems to me a good thing. Unlike divisive userboxes, the autograph books seem to just be about saying hello and being friendly.
Hey, Ramesh you have a nice page. It's great!! Nice to meet you. Wanna give some of your time to mine?! Also you are a good user. Go on like this. --Pratyya(Hello!) 14:57, 24 September 2013 (UTC)
I will replace {{not done}} with {{done}} after each guestbook that I have signed. Note: This is not the place to add your guestbook because I signed it. Only add it here if I haven't signed yours.
