Why is http://todaysvisions.com so slow loading?

Hey y'all - this was exactly why I went for the monthly right now rather than the yearly. Just in case this platform did not meet my needs.

My site is running so freakin' slow it is not funny. I cannot invite others to start a blog on the site until I can get the performance up. Problem is, I do not know of any other way to do this besides wordpress.

I installed a caching plugin - Super Cache to try and help - and it did, a little.

I really need help as soon as possible.

Thank you so much
