0.10 is now stable and already on 0.10.2 (https://bitcoin.org/bin/bitcoin-core-0.10.2/).

I was confused that bitcoin.conf wasn't there, wondering if something had changed. But it turns out you can just create it (coming from: https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File).

When I go to [`http://blockchain.info/hub-nodes`](http://blockchain.info/hub-nodes) there are no nodes listed.  The page has headers for information such as IP, Relay Count, etc but no actual data.  In the sites footer there is a link to [`https://blockchain.info/connected-nodes`](https://blockchain.info/connected-nodes) is this the same thing?

Does this answer apply anymore to bitcoin core version 0.11.2?  Under Windows 10 there is no Bitcoin folder anywhere under AppData.

For fun & learning only ... another little hack - https://github.com/alphaaurigae/log-est-connections  - with the script you can log ips on a specific port to a file. Theoretically one could use it to compile a list of add nodes / seed nodes . However, i feel this might be against some crypto basics not centralizing the connections. Use with care. Additionally, heres a sed script sample to modify the crypto source for more connections - however . your node will be marked "dirty" of course but makes thousands of connections.

To download the blockchain with maximal speed you want to be connected to nodes with high bandwidth. 
On default bitcoin will search and connect to random nodes. One can add nodes to bitcoin conf to tell bitcoin to connect to specific nodes.
To add a node to the bitcoin client to connect to, add the following to the bitcoin.conf file in:
Windows:/appdata/roaming/bitcoin/bitcoin.conf
Linux: $USER/.bitcoin/bitcoin.conf
ADD THIS TO BITCOIN.CONF
addnode=127.0.0.1

To find high bandwidth nodes go to: 

blockchain.info/hub-nodes

for example and browse the hub nodes section.
It is not required to add the node port, bitcoind will find the correct port.
