I think the sidebar is missing some relevant information, particularly the links and wallets section. I propose it be replaced with something like this.
Information
Wallets
A list of popular wallets can be found here.
Mining
The easiest way to get started with mining is by following the Gupax guide. More advanced users can read How to mine on p2pool.
Exchanging
A list of popular exchanges and swaps can be found here.
Wasn’t aware of the bounties site, thanks for sharing.
I also prefer this compact information compared to the old reddit sidebar
