Great to hear that Pillen is putting good internet access to rural areas. I believe that is crucial for small town Nebraska. I question your statement that Red Cloud is vibrant. You know more than me, but when I pass through there it seems there is little to no growth. In fact, it looks like it is eroding. It had a population of 1531 in 1970 and has consistently lost population since. It had a population of only 962 in 2020.
Some of these towns need to come up with a theme or exploit something they make or produce. Create a festival or an annual event. Here in Eastern Washington a lot of towns promote ag products and wine. Nearby Leavenworth, Washington (pop. 2,263) was afraid of fading away after the lumber mill closed down and logging was slowing down back in the sixties. With no German heritage the town leaders encouraged the businesses to all change into Bavarian architecture. Leavenworth is now famous for Octoberfest, Autumn Leaf Festival, Christmas Lighting Ceremony and having plays in the summertime.
