Intelegent beings learn from each other

I don't know how the intergalactic net got started, but it uses the part of the radio spectrum between micro waves and infra red light. Each packet of slow speed data is about 67 minutes long. It is typically a technical paper written in the language of the author. Before the main text is a math lesson and a language lesson to help recipients translate the tech paper to their own language.
Typical net partners receive these packets 24/7 from 3 different directions from sentient outposts up to about 144 light years away. They transmit packets to the same three net partners 24/7 Mostly they relay packets they don't think their net partner has received lately. An estimated 517 billion unique packets are in the system, perhaps 755 billion duplicates, with about that number enroute at any given instant. (most with lots of minor errors) (it takes 144 years for a packet to travel 144 light years) About one millionth of the packets received are packets that were first sent millions of years ago, so these contain valuable historical data even if the technology in the paper is of little interest. Occasionally a net partner gets back something they sent out long ago after being relayed many times. If they still have the original it is interesting to note the effect of being relayed thousands of times.
The program is moderately costly, and only an occasional gem is received, but most agree this is best as it avoids cultural shock = technology and customs changing at an excessive rate. How might the galactic net be done differently? Neil
