Which cryptocurrencies are now more profitable to mine than BTC?

[malevolent]

Are there any, is merged mining available for all of them?

What about cpu-based ones, e.g. Litecoin? I couldn't find any mining hardware comparisons and profitability calculators for mining alternate cryptocurrencies, how much money (in $) would I make from a Q9300 @ 3.5 GHz per 24h?

They're all less profitable than BTC, which makes sense I suppose.

Per watt, LTC is about a third as profitable (see coinotron), although I'm not exactly sure of the validity of their calculations.  The main reason to mine it is if you have idle CPUs in clusters for mining bitcoin and you wish to make use of them somehow, and power is cheap.  If the network eventually stabilizes, I would expect the price to rise about 200-300%.  At the moment, it's been heavily botnet mined and these people dump whatever they get into the market.  Now is a good time to mine BTC and then use the BTC to buy the LTC.  I have a feeling soon the price will come up when people take notice of the disparity.

Merge mining makes this question irrelevant (except for the CPU focused chains such as LTC). With merged mining, you get other coins in addition to your BTCs. Go try out mmpool.bitparking.com. It'll give you NMC, DVC, I0X and ICX in addition to the BTCs. After mining, either keep those alts or or speculate with them on Vircurex.com.

What about Cosbycoin?

Anyone who is mining 'other' coins, are just trying to make a quick buck, they have no interest in the currency succeeding.

Why would you need another currency? the main one 'bitcoin' is not yet fully successfully in its goals.

Stop trying to get in 'early' on something, if you missed this with BTC, just enjoy it now as an online currency.

I assure you 100% you are wrong.  I have never exchanged my Litecoin for Bitcoin nor do I plan to, however I do plan to at some point buy some Litecoin with Bitcoin to support the miners efforts on this side.

Interesting talks regarding 'other' coins here in this article http://bitcoinmedia.com/luke-dashjr-throws-book-at-solidcoin/, worth reading the comments too
