I have an account with onlywire which allows me to bookmark sites on 20 social bookmarking sites. Only problem, is I cannot bookmark my same sites more than a few times. So if you have an account with them, or wish to set one up for free, I'd be happy to exchange a few bookmarks if you submit my sites/s on your onlywire.

Of course I submit loads of random sites as well, just to make it look legit.
