There can be reasons why a startup like Twitter shouldn't turn on the revenue right away. There are posts about this on
http://www.techcrunch.com Wombat: Yes, there used to be (still are?) two versions of assetbar. One is free, the other is pay-only. You can still get to the free one, even though it's broken... go to achewood.com, and click on "discuss." it shows you a blank page. it used to show you the free assetbar.
It is a mistake to say that the free assetbar was not bringing in revenue for Onstad. Every bit of content that you put out there for free is fodder for public discussion about you. The idea is to have your content floating out there in whatever system people use (google, youtube, the school bus on the way to school, etc.) That way, people who have never heard of you may be exposed to you when other people talk about your content. It's also a good idea to have plenty of free content on your site, so that people form the habit of hanging around your site. The longer someone hangs around your site, the more likely they are to form a connection to your work, and to buy something. Even if the free content on your site isn't directly about your work very much, as the free assetbar wasn't very much about Onstad's work, it still served the purpose of giving people some reason to hang out and so absolutely yes, it had to bring in some revenue from people who otherwise would have read the achewood strip and then gone away and forgotten about it.
Of course, I can see assetbar being a liability because anyone can post anything on it and it's poorly regulated. While that is part of the charm of assetbar, it is also a liability... but anyway, assetbar is content, and it was free. (at least the free version was free.) So in providing free content, the free assetbar was an asset.
The trick is to determine how much content you float out there for free, and how much you want to charge for.
Obviously, if an artist decides to force the take down of every possible copy of their work everywhere, then that artist has no exposure anywhere and may slip into oblivion. If on the other hand the artist allows high-quality copies of her work to be reproduced everywhere, then few people may pay for authorized/licensed copies.
I logged in and tried the pay-assetbar after the free assetbar went down a few days ago, and I wasn't happy with the interface of the pay-assetbar. You got to look at the stuff that Onstad posts, but if you wanted to use it as a discussion forum, the interface was actually more kludgy and difficult to use than the free assetbar. If you compare the discussions in the free assetbar to the pay assetbar, the discussions in the free assetbar are much more extensive. I think that is probably due to the interface on the free assetbar being easier to use and being more responsive.. it's less clicking and scrolling on the free assetbar to have a discussion than on the pay assetbar.
Some people might prefer the pay assetbar, but I think that the possibilities of the interface are absolutely different between the free and the pay versions, and that will impact what kind of content is generated, and how valuable it is for the site.
