My blog has been really slow to load as well as of late as well as a friend of mine’s.
We have been blaming our webhosting for the problem, but have not been able to figure out what the cause of it is.

I am not using the wp-cache, but have tried optimizing the database. It is definitely something with accessing the database causing the slow down, but I don’t know enough to know exactly what is doing it.
