When I was in Russia they charge by the megabit for internet usage. Other places in the world function similarly and it's usually not a big deal but one thing I noticed is that there wasn't a chance I was gonna visit certain people's blogs who have them setup poorly. What I'm talking about is the blog page that never ends! Ya know those blogs that load and load and load and it's like the last year of this persons life.
If this is you FIX IT!
There's a setting that lets you set how many days to display - set it to seven days max...and if you're one of those people who likes to put 85 pictures in each blog post maybe set it to three days. After that let people use the archive to find what they want.
