New Taproot activation proposal on the mailing list "Speedy trial". This looks like it could progress in Core. If your top priority is getting Taproot activated, I'd encourage supporting this. If your top priority is LOT=true over getting Taproot activated I can see why you might oppose this. Personally my top priority is Taproot activation.

This new idea gained a lot of support on IRC yesterday:

Basically: very short timeout for signalling, so we quit early if it doesn't work and can go on to try something else, but still a big delay between lock in and actual activation of rules on network.

At least once a week, somebody on the street tries to sell me cannabis. I'm sure it's because of my long hair (and maybe my beard and frequent sandal wearing). What's interesting to me is how many unique people have made me this offer. I'm wondering if there's an algorithm I can use to estimate the population of local people with a pot-selling side hustle based on the frequency of my encounters, the number of hours I spend in public, and the local population density.
