People are invited to invest in the actual product and technology, Steem and Steemd. Not SteemIt which is really a proof of concept frontend implementation as I said.
The Steem Dev team have already said before that they expect the community to make the best frontend for Steemd (the actual tech that provides a product that consumers utilize)
In my opinion, investments to SteemIt.inc are more wisely used on the development of Steemd, not the website that they don't even really have intentions on maintaining.
I do agree that the white paper should be updated to match current values and the state of the network.
Still, the SteemIt website is in a public repo. Go make feature suggestions because your ideas aren't bad. But expecting a small under resourced team to have the time and desire to implement the little things before the community really asks for them is silly.
