Steem has a vesting and liquidity rich list at http://steem.synergycoin.com/richlist.html
The default list is vesting, but the liquidity rich list can be selected by clicking the 'Balance Richlist' button.
This was actually the first community provided service for Steem (and may very well have been the first service for Steem in any way).
Thanks to the SynergyCoin team for hosting this!
