Ah, Twitter. The birthplace and cemetery of many a beef. Today Wale and Kid Cudi joined the ranks of many who have buried the hatchet from behind their keyboard. The two had a few problems before but it reached a peak when Kid Cudi spoke some choice words about Wale in a 2010 issue of Complex. The two had once been very close so the beef was quite a shock to some. But today, all is well in the world of GOOD and Maybach music. Hit the jump to see their Twitter exchange and even alluding to a possible collab in the works? @MarisaMendez
