i have one hub that was viewed almost to 2000 in just one night upon spreading it to the internet cosmos. And then I have those hubs which currently only having 2-5 views a day.
I guess it depends on a particular hub.
I remember last week when "Dorsi" published her "strange sound hub", it got more or less 10,000 views that single night.
Make a hub that would interest all of us. One hub that is irresistible. I'm sure you'll be pleased with the outcome.
