The moviebob thread is as much about reacting to his retweets on BlueSky as it is about Bob these days.
I think what separates the wheat from the chaff when it comes to lolcows is how much they fit the "cow" part. Using Bob as an example, there were plenty of lols, but he's just smart enough to realize (after getting fired twice and being stuck back on YouTube where his videos are ghettoized to all hell) that, on some level, his prior behavior is what got him in trouble, so he retreated into safe hugboxes and languishes in obscurity.
You get three kinds of lolcows, in my experience:
The massive O-type: Burns furiously bright, but is short-lived. The cow earns a ton of attention really quick, acts out, but then they realize the attention is only going to get worse and disappears (or, more likely, family intervenes to tell them this). Gold standard, for me, is Alison/Jake Rapp. About 18 months of lols and then they disappeared off the internet.
The red dwarf: Never burns super bright, lives forever. Maybe a brief flash upon discovery draws the initial fandom in, after that they just chug along. The level of chugging is either enough to sustain attention or they diminish over time as people lose interest in the same old, same old. Bob's in this tier, imo.
The neutron star loop: keeps bursting and collapsing into new and interesting things. The appeal of the lolcow becomes how much they constantly switch gears. Fuel for long bouts of drama and content. Anisa Jomha, enough said.
O-types are short-lived by their nature. Red dwarfs have a long tail to their threads, eventually they will peter out. The neutron stars, in some way, thrive off the attention and start scrambling to keep it, consciously or not. They'll be around for a long while until one of the supernovae ends in them landing in the other two categories.
