I don't know about project/product lists, but you could look to https://code.google.com/p/protobuf/downloads/list - 50,000 downloads of protoc 2.5 since late February, which suggests reasonable usage - and that doesn't include packages that either don't use protoc, or which embed protoc. You could chalk up at least another 13,000 just from the most recent version of protobuf-net (nuget+googlecode downloads), but there are many other external implementations ( https://code.google.com/p/protobuf/wiki/ThirdPartyAddOns) - perhaps that list is a fair measure of community uptake.
It is a core part of many internal google APIs, and a few of the public APIs. And more anecdotal: it has certainly featured in most projects with a need for serialization (persistence, network, etc) that I've been involved in for the last few years ;p Marc -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
