implementations

1. The "Implementations" section would be much more useful if it distinguished between complete or nearly complete implementations on the one hand, and all the others. A three-way categorization would be fine if you think a two-way scheme might be too harsh, but a two-way classification would undoubtedly involve less subjectivity. Please note that some of the "implementations" mentioned do have strong disclaimers about being incomplete or experimental, so you might want to base a classification scheme on such self-descriptions.

2. fq (https://github.com/wader/fq) is mentioned under "Tools" but it is a substantially complete implementation of jq (it is basically an extension of gojq, which is listed under "Implementations"). It would be very helpful if fq (like gojq) were listed under Implementations, and preferably grouped together with jq and gojq as "first tier" implementations.
