Eldritch Glaive from Dragon Magic is usually considered a better option than Hideous Blow, but in general a melee warlock could be pretty fun. ^^ Just make sure to get that item that increases the amount of damage your Eldritch Blast does, so you won't have to worry about falling behind on damage output.<br/><br/>I do think that going for a more general melee build would be a better option, though.  Spirit Lion Totem Barbarian for pounce, being Large-sized would let you get Knockback (http://www.realmshelps.net/cgi-bin/featbox.pl?feat=Knockback), work in a few levels of Fighter for the Dungeoncrasher ACF...  You'd get to send opponents flying with each hit, and get respectable damage for knocking them into walls. ;D
