Opt-in or No Opt-in

I created my first list-building blog with a strange feature:

No Opt-in necessary.


Now, many of you would understand why I thought that would be better in the long run. For others, here's why:
-------------------------------------------------------------
1.Forced opt-in would only get me a list with most members not interested in what I would have to say later, since the subscription would be like a one-time pass for getting a few freebies.

2.Instead of a 1000+ non-responsive list, I would on any given day of the week prefer a 100 member responsive list.
-------------------------------------------------------------

As the first week comes close to its end, I have only 8 Email Subscribers with the successive days getting me:
Day---- Subscribers--- Pageviews--- Visitors
1 -------- 3------------- 20----------- 7
2 -------- 3------------- 132--------- 41
3 -------- 1------------- 59---------- 20
4 -------- 0------------- 34---------- 11
5 -------- 1------------- 53---------- 19
6 -------- 0------------- 58---------- 14
7(so far) - 0------------- 40----------- 8

While I have made a few modifications to the site layout, I don't think it could have become so different as to drive away potential subscribers.

***One point to note is that 90% of the visitors were from Warrior Forum.

Please take a look at the site and point out the changes I need to make:
