What's the point of adding DGB to Cryptsy? Everybody knows about DGB by now. Cryptsy is the biggest coin killer online. (People buy before, dump at Cryptsy).
Just the fact that there is a lot of "new money" on Cryptsy. Being listed on an exchange with that amount of BTC volume is always good. Sure there will likely be a dump, as with all additions. But from there the coin can grow.
Edit: On second thought, with all the new buzz, if it happens today... The "dump" may not be nearly as epic as some of them. People are just hearing about it still, suddenly appearing on Crypsty could spark some decent buy power to offset the dump.
