I don’t know if it was a stupid idea or not but market will tell if a search based on number of followers (or other filters) makes sense or not. In any case I am very impressed by how fast the developers behing twithority and twitority delivered these services, both in less than 24 hours, I just love the Internet. Congratulations to the developers who made both of these and thank you so much for jumping on that idea so fast.
Now I bet that Twitter will integrate some form of filter based on some kind of “influence” based search -to avoid the “authority” controversial world so many people hated- in the future. In the meantime I will bet these services will get some traction.
