According to Jason Kottke, “companies and people will be able to purchase tweets that will show up first in certain search results or right in people’s tweet streams. Which, if you rewind the clock a few years, is exactly the sort of thing that used to get people all upset with search engine results.”
I don’t want advertising in my tweet stream, as I suspect most people who use the service don’t either. I understand Twitter’s need to generate revenue as a business, but I would suspect Twitter aps would create plug-ins to block this advertising from showing up.
Good idea in theory, but it’ll be interesting to see how it’s implemented.
