It's really easy to get my real identity given a website that I own and I don't have a non throw away account.

I use a throw away account because it gives me the freedom to discuss things openly without being judged based on my real world reputation or which company I work for.

Then the account you're using is not a throwaway, but you could create an actual throwaway to post it :)

I've been told this before :)

My thought was to throw it away initially but I have so much karma on this account I can't bare to part with it.

So don't! If you create a second account for your business identity, nobody will know. Keep business and personal accounts separate. Neither is throwaway!
