Over my career, I worked on many different mainframe systems (IBM "big iron") and with many different commercial applications. No matter which system or application, we were always involved (either passively or actively) with the associated "user group".

For IBM systems (both hardware and software), it was "Guide" (http://en.wikipedia.org/wiki/GUIDE_International) and "Share" (http://en.wikipedia.org/wiki/SHARE_%28computing%29). Other applications and services had their own user groups.

I can't comment on the trend to dispensing with vendor-support in favour of user-group support, but I can assure you that user-group support has (for decades) been a staple in the industry.

Two elements of TFA caught my eye:

  1. The object radiates at "around 225 – 260 Kelvins", or (if I got the math correct) 12.878971111111
    micrometers
  2. the object "has a very low mass, too, probably between 3 and 10 times the mass of Jupiter".

Together, these figures are within the range for a type I (or, maybe even a type II) Dyson sphere.
And, it is only 7.2 light years away?

Yes, it is very probably the Brown Dwarf that the astronomers think it is.
But, imagine. It could be a Dyson sphere; our first evidence of advanced life beyond the earth.
