I came across this awsome site which makes the voting process automatic or favs for your social bookmarking sites, and it won't cost you a red cent!
Automatically get as many Diggs or votes, whatever the particular bookmarking site calls it, as you want.
manage your bookmarks stored at del.icio.us. one hit batch mode re-tag bookmarks en masse, make wholesale changes to URLs or update descriptions in bulk. toggle public/private sharing settings and mass delete bookmarks.
Imagine you have hundreds (or even thousands) of webpage URLs that you want to upload to your del.icio.us account. How would do this bulk submit when the delicious system allows you to bookmark web pages one at a time ?
