EDIT: In case you aren't familiar with OData, here you go.
I am trying to determine whether it is worth learning this technology or if it is something that is not going to catch on.
The premise is interesting, and as a developer of APIs it seems like a good way to offer more flexibility to the developers that consume them.
Unfortunately, I am not seeing much "buzz" regarding Open Data Protocol in the past couple of years so just trying to gauge if it has any chance of being around once I learn it.
