The only thing is I'm there every day, same hours,
Visiting the site once per day (at roughly the same time) still makes you vulnerable to missing a day. Here's why:
Let's say in your timezone (as an example) you visit around 12:00 in the beginning of January - this is by chance the exact same time that day counter on Ask Ubuntu switches to the next day.
Let's then say on the one day, you visit at 11:59, and the next day you visit at 12:01.
Now, the first day you visit will be registered as January 1st on Ask Ubuntu. However, since you didn't visit in the interval 12:00-12:00 the following day, you next visit at 12:01 will register as January 3rd on Ask Ubuntu.
If you want to be sure this can't happen, you need to visit twice a day with 12-hour intervals - then this will never happen.
