I know that this may seem like a simple question, but how many posts do you have displayed on your front page? I have went between having five to having ten. And then I have gone to some blogs that have up to fifty posts on their main page.
I started with 7 which I think is the default amount for blogspot. I am now down to only 4 because my blog was loading slower than I liked so I wanted to have less to load. I don't think there is one right amount, a lot depends on the length of your posts.
Interesting question Shynea. I am interested to see what other bloggers choose to do on their sites.
I think I have seven on my main page. I want there to be a variety to topics and posts when a new visitor stops by on my front page, but I don't want the page to take forever to load. I am not always likely to look through posts that aren't on the main page the first time I visit a blog, I usually check out what is on the first page and decide if I am interested enough to come back.
