Twitty Limits - a Biz Model for Twitter and other SocNets?

Twitter is limiting those any one account can follow to 2,000 apparently (picked up off Dave Winer's blog)

Dave sums it up succinctly, no need to add to this:

1. My first take: Probably a good idea.

2. Is this a problem for people?

3. Confirmation that the expensive thing in Twitter is distributing status messages to large numbers of queues.

4. A business model appears? If you want more than 2000 followers, that'll cost you $X per year per thousand?

5. If no business model then here's something you can't use Twitter for. I had the idea that it would make a good medium for delivering hot news bulletins, and have set up a few channels for doing that. But if they can't grow beyond 2000 followers, there's not much point investing.

6. Or is it a method of keeping malicious or annoying Twitterers in check?

Its certainly the business model we (among others I hasten to add) suggested some time ago. Re item 6, anyone who wants to use it as a broadcasting system is abrogating its original design and is probably a business - so pay up! (Its a way of increasing transaction costs to set a minimum bar against total drivel). We also suggested a certain amount of free posts a month, then pay or be quiet as a way of limiting the drivelers.

Also seems a good number to use to cull those who follow us.
