I dont know, as soon as it comes to front-end I have my ideas fixated on politics and how you could sort and browse political content better. But this is not my WarzonePolitics project....
I think it is a smart idea to sell some POB to stabilize the price and to fund something that actually has value to the community.
I have read the post you linked but I couldn't see anything that got me excited. Most of what is suggested I can already do on hive and while it would be nice to have the POB frontend completely replace the old hive frontend, I would really like if it becomes more than peakd with different colors.
I dont really got ideas of my own but I like that @gilleanpearce brought up the old topic of having a good search engine.
I agree i am getting a bit sick of switching front ends for different features would be great to able to use pob for 95%... maybe even an app? To far i went to far
