I know of 323 IXes today.

In my experience, there are a few states that local exchange "markets" go

First, no exchange, or something which claims to be one but isn't.

    Then, inspiration strikes someone, and:

Second, there's an exchange, and life is good.

    Then, idiocy strikes someone else, they determine that the existence
    of an exchange "validates the market" for exchange services in that
    region, and:

Third, multiple exchanges spring up in the same area, tearing apart the
switch fabric and ruining the economic reason for peering in the first

    Then, people grow to understand the market, and:

Fourth, the different exchange-like services differentiate sufficiently
that people can use peering-oriented exchanges principally for peering,
and transit-oriented exchanges principally for transit.
