I actually bought a subscription to Slashdot last Christmas. I paid for the minimum 1,500 pages, thinking that with care they would last me 3 months.
It is now 4 months since that purchase, and I've used a little over 33% of the subscription, despite having liberalized my use of the ad blocking, etc. I'm on slashdot at least once and usually several times a day, I read 6-12 articles per day, I sometimes make comments, and I metamod about once per day. (I haven't seen moderation privileges for more than 2 years despite "excellent" karma).
Such a deal.
