For the most part, Humans of Trolleybuses relies on its community. "At the height of the page's popularity, it was receiving about 15-20 funny photos per day," Rokas told Bored Panda. "To decide if a particular picture is worth a post, I'm trying to figure out whether it would enrich social media or trash it. At first, I consider the originality of the photo/video. It can't be a repost or something lame in general as the idea behind the project is to create unique, independent content that isn't toadying to anything or anyone."

"Ideally, the photo/video makes up for about half of the entire gag. The other half is the caption, so, the more interesting and abstract the image or recording is, the more freedom there is to create a captivating caption."

"The best captions usually come spontaneously, during the first viewing of the submitted material," Rokas added. "If you're overthinking it, it might end up too complex, forced, and only you and a couple more people can understand it. I don't have one rule on how to craft the perfect caption, I just try to feel it out, make it something that compliments the picture/video without overpowering it."

Today is also a tougher period for Humans of Trolleybuses. Rokas attributes the lower number of submissions and posts to the transition the page is making from Facebook to Instagram. "I believe that it's only a matter of time before the project becomes what it recently was."

He thinks that many people are drawn to Humans of Trolleybuses probably because they relate to the trolleybuses themselves. "It doesn't matter how uncomfortable or slow this mode of public transportation is. People sympathize with tit and people need quality content which can also be funny."
