Google seems reluctant to release an update to the penguin algorithm. Anyone think they are having a hard time getting it to work? I know some people might think they don't want websites to recover from past updates but the flipside to that argument is they would want to also hit sites that are clearly using spam links to rank. Also when do you think it will be released? I've seen some people guess it might be around October like past releases but that would be around 2 years since last release.
