I have an addictive personality (and I am also a completist). I don't know whether I am hard-wired this way or whether I was dropped on my head when I was a baby. Whichever, it makes for an, umm, interesting life.
My latest addiction is keeping an online food diary. And it's working; I'm losing weight. Finally, a healthy addiction!
When I find something new that fires up my addiction, I have an intense frenzy of activity.
Here are some of the Internety things I have become addicted to, and in more or less the order they happened:
e-mail: when I met Frank
Usenet: discussions and socialising
nethack: a terminal-based (text characters) dungeons and dragons game
selling on eBay: documenting page hits daily to determine patterns and reviewing number of watchers on an item
Visit detail: for my company and personal web sites - pages displayed per visit
Flickr: reload the page of recent activity on my photos
(I now get this by RSS)
Second Life: chat and making my avatars lovely
Askville: reviewing answers to my questions (I left after a couple of weeks)
Facebook: reading friend status messages
(I now get these by RSS)
Ancestry.co.uk: researching Frank's family tree over the xmas holiday, once staying up 30 hours
FoodConfessional: documenting what I eat
Oh, and making lists.
And, because I am a completist, I will be updating this with more things as I remember them.
