I personally see NO reason to work on a fancy new front-end now - the community is too new and needs a stable community and from a marketing perspective a "story" first, i know I said that already and I know you said "anything people post that has been created with brain" is kind of allowed and what PoB stands for. But that is too open, we need a bit more core story and key differentiators vs. all the other tribes here in the Hive ecosstem and social media blockchain / crypto platforms outside. When story and strategy are defined think of a new front-end - then develop it and do proper marketing.
Liquidity will come as many folks will use the tag anyway, hope not too many shit posts will come - which brings me back to: We need core story and positioning of PoB.
