As a gardener, who is constantly taking photos of my plants and tagging them, I noticed the same pattern while generating stats on all the tags collected over time.

The frequency of photos would increase when there was flowering, fruiting, growth spurts, interesting leaf growth etc but the plant would get totally ignored for long periods if its neighbour was doing something more interesting or if it was struck by diseases/bugs, wilting, dying etc.

I also realized my least photographed subjects are weeds. Even though a lot of time is spent looking for them and managing them and just being gobsmaked at how unbelievably good they are at surviving whatever the universe throws at them.

I have a dumb script that generates a periodic report on all the tags to tell me which plant/tag hasnt been clicked for a while. It hasnt really made me a more disciplined but I feel its constantly reminding me of what I getting bored off and where my interests lie.
