For the love of FONTS!

Ok, I am so sorry about the way this font is coming out. It's totally different then what it's like while I'm creating the posts. There's always hiccups when setting up a new site, and I think I may have found mine!  I am looking for new fonts and how to change the posts' font however.
Thank you for your patience, as I know this is hard to read as it is!

How do we like this one folks??
