I state that I run BU on my server: icarus.tetradrachm.net. I would like to generalize on the question of the benefits of knowing which server you connect to. Originally, I switched. to Electrum when I read that Jaxx discouraged sending mining payments to their wallet addresses. This lead me to suspect that my Jaxx wallet would trust a central server.  Since I ran a full node in any case, I decided to run electrum-server beside it, so that I could connect to my trusted full node. However, it sounds as though since electrum uses SPV which eliminates the profitability of a sybil attack, I could use auto-connect with little risk.  Also, by using electrum in contrast to Jaxx, Mycelium, et. al.  I connect to a full node in a more decentralized manner.
