Don't be a bit concerned, be a LOT concerned. Drop it immediately
Clearer.info is interesting, but I see better ones not-selling and dropping all the time. xx if you get a somewhat interested buyer who likes it for some specific use.
Satires.net same as above. I see a lot of similar quality dot.net available these days, even when the dot.org/info and others are taken I see the .net still left available for decent names. Value - xx range if someone's interested.
