Here are some graphs I made from raw data the blockchain.info shares. All graphs include averaged values with the last 200 before them, so that huge peaks don't destroy the whole image.
1) All data
2) Filtered by min age 1 week
3) Filtered by min age 1 month
4) Filtered by min age 1 year
I'd say it's going up!!! What say you?
Edit:The 1 year chart was misplaced and fixed, sorry!
