Eh, it's just not the same if it goes "poof" when you close your browser...
It is for me. As DM primarily, and player secondarily, I have perhaps made 200 different characters since 4e was launched, if not more. I do however only have 11 or so on my computer. The one I play, a handful of characters I would play if my ranger died, and a copy of the characters in my own campaign.
Everything else, I never save. I might make something, just to see how it looks, but I do not see an absolute need to save and save it for posterity. I seriously doubt that those people who have hundreds of characters ever get to reopen most of them.
Look, I am not saying I think 20 is more than enough. I think its too little as well. 50-100 should cover people's needs without risking any issues. I also bet they will up the limit quickly.
I am however saying that some of the people complaining about their "needs" for hundreds of character slots are (grossly) exaggerating said need. IMO, of course. But hey, it's the Internet, the place where restraint doesn't exist.
