Similar to BitTorrent trackers. Or are all peers equal in ability and importance?

There is a node that will relay all transactions, regardless of whether a fee is paid:
There are well-connected nodes that are recommended for use by merchants to avoid risk to a race attack. Some of them have inbound connection whitelists so as to lessen the risk of intentional address list poisoning.

1Is there a common location listing the well-connected nodes? Or how can I get a list of these nodes? Commented Jun 20, 2012 at 17:52
The Fallback Nodes can be considered to be "super nodes", as clients will at times use them to get a list of peers. Similarly, any node operated by a mining pool or a major Bitcoin website should similarly be able to provide more accurate information than a regular node (by being connected to much more nodes).

2That list of fallback nodes is not the same as the list of seednodes built into Bitcoin.– theymosCommented May 17, 2012 at 19:49

@theymos Hmm, this is new to me and I can't seem to be able to find a Wiki article on the seednodes. I'll make an appropriate question... Commented May 17, 2012 at 20:34
