I think that the lack of responses are in part due to Bannen's thorough response.
I tend to agree with him for the most part.
I had actually registered geolocal.io at one point but let it drop because it ended up being something I didn't want to maintain in the collection

To me it works as a functional name but not one that is broadly brandable. It could be the foundation of many a business but it seems to be more in a service provider manner rather than a consumer product company. Think platform, think service. A company in the business of geolocal marketing should really want this name despite it being what I consider a generic.
I think that in the end I prefer the direction of proximity marketing which is more consumer driven (beacon names as well) but most people don't know the difference so you're not going to get great reseller value which I think Bannen indicates as well. I tend to think geolocal is still sounding a little dated.
I would never settle for $5K as the name has a much larger upside than that price would ever suggest. I don't know what the high-end is but it will be determined a lot by your patience and pressure you feel to sell. I would think even low $xx,xxx is not what people would call a motivated buyer. This is a category killer and if you can, and time permits, you should hold out for more (unless you see the term losing steam which is possible)
This is all theoretical - the name is good enough that you should have received offers. I would expect by now you should have received offers in the low $x,xxx range and probably a whole lot of $60 offers. For all I know you've received offers in the higher range.
The number should give some indication of the actual desirability that you can use as a better basis than public opinion here.
My immediate thought was that this is a 20-30K name but I'm sure others think that's high and some will think that's low (and I'm second guessing) because that's how opinions works. Continue to keep the .net and .org. .The org in particular allows for an open source / free version branch of any platform and, as suggested, that's how I see this name used.
[Update - being a bit stalkery]
With your area of expertise being Digital Marketing and part of a group previously called GeoLocal Media I wonder why you need assistance valuing this. I don't know why the name is not functional anymore but you must have first hand insight of the value.
