I use livejournal.com, I used to have blogspot...or blogger. But copied over all my stuff to livejournal. Ummm archiving I don't use that much.
Here is one example of the archive, each red number is how many enteries they had that day http://www.livejournal.com/users/cbradfield/calendar
... now, when you are logged into the program thingy...you can manage your enteries better. What do you want/need in archiving? When I manage...it can recall the most recent entry, the last 20...or however many you want to show (with a max of the latest 99), or search by certain day.
Maybe you need a database instead...???
I say...sign up and try it out. Hope this helps...
