There are honestly enough freerolls running out there (outside of Cards Chat), you can play for 16 hours straight.
If you're trying to zero to hero, or just splashing around for fun, some good freeroll listings out there, first google result accessible kinda thing.
partypoker alone runs 24/7 freerolls that will get you entry into some micros. I turned one of those $20 PP freerolls into a 75K GTD entry, definitely not worthless.
I am always down for more free money, but contrary to popular view, I do not enjoy the lottery style super turbos, turbos are tolerable.
