There you go and that's good that you are being honest on your thoughts about your collateral. Here is my take on what you are offering and I hope you don't get offended with this. Your Blog as you say is not worth the amount you are asking and you know that so if someone lend you 1BTC against your Blog then you hit the jackpot, you don't even have your own domain name for your Blog so if ever (not saying you will) you run away with 1BTC the lender will end up with a Blog that he cant sell to recover the 1BTC loss.
