There are currently 195 questions tagged with newtonsoft. Per the tag wiki:
NewtonSoft is a software label by James Newton-King, author of the JSON.NET object serialization library.
However, all of those questions are not asking anything about the software label, per se, but rather asking about the product: JSON.Net.
Do we still need the newtonsoft tag, or can we merge all of existing questions tagged "newtonsoft" into the tag json.net?
