Do you think I am having too much of giveaways?

you could divide them forum vs blog if you feel it´s to much for your blog
that way attracting members to sign up and remain and possibly be more active,
moreover give feedback, maybe there is still a problem with this?

I honestly don't think you can have too many giveaways. I don't enter all of them but that has nothing to do with the frequency of them. It just has to do with If I use the program or not.
