Hello, Umby. Lotso directed me to this thread.
I've been talking to several TF2 streamers, including almost all of the top non-comp streamers that show up in the TF2 twitch integration window. It looks like Twitch integration might be good vehicle for promoting custom games and custom maps, elements of TF2 which were once commonplace but were devastated by the saigns/NighTeam fiasco several years back.
I don't know how much of an audience you have, or how many other Twitch streamers you know, but have you considered running custom maps or custom game modes? Personally, I'm a fan of custom maps, not so much custom game modes, but you do whichever one you prefer.
You could even show up to the games of other streamers wearing the FP tag, but without your Twitch URL in your name. Players wearing their FP tags would bring attention to this server community, and hopefully other server communities as well. Heck, yesterday, even the infamous GEWP (Gibus Engineer Wildlife Protectors) hosted what would've been a 12-hour stream. Unfortunately, the streamer fell ill and had to stop at the 5-hour mark to rest. Perhaps FP could do something similar but more respectable (I like to think we FapPowered motherlovers have higher standards.)
