I checked recently the JSON RFC, which explicitly forbids Infinity and NaN.
See here: https://tools.ietf.org/html/rfc4627

"Numeric values that cannot be represented as sequences of digits (such
as Infinity and NaN) are not permitted."

Even though some implementations allow it, I tried to process a JSON
structure which contained Infinity with javascript and it raised an

So, for these two reasons, and because NetJSON would be based on the
JSON RFC, it probably makes sense to explicitly forbid links with
infinite weight.

It would also simplify a lot consumer implementations, which is
something I believe we should strive for.

What do you think?
