I like hotmetaltype because I am oldskool and remember HoTMetaL with fondness. 8-) But I agree I'm not sure it would convey the right image if you don't have that or typesetting in mind ("hot" and "metal" possibly have too many other connotations...).

burnishedwords is nice, sounds quite classy. moltenwords sounds more chaotic and a bit emo-poetry IMHO. (Free-associating out loud a bit here, sorry.)

I agree that wordworksweb is the worst of the bunch I'm afraid -- hard to say, hard to remember whether it's wordwork or wordswork or webwordswork etc etc.

I am now trying to resist the temptation to compound the problem by brainstorming more suggestions around the blacksmith kind of theme (wordsmithy? wordmelding?) as I don't think more choice will help you make a decision. :-}
