The blog post also contained the following disclaimer:
Tumblr Labs are experimental features that were designed and developed in someone’s spare time. Labs experiments are not guaranteed to work the first time or any time. Labs experiments may abruptly and unexpectedly cease functioning or disappear altogether. Real features are not regularly tested for compatibility with Labs experiments. To disable a Tumblr Labs experiment, turn the switch off. New Labs experiments will be added and old ones removed, possibly (probably) without notice. By reading this message, you imply a positive disposition towards Labs experiments as long as they last and accept that things will inevitably change as time moves on and on. Labs experiments have not been tested on live animals, your taxonomic rank notwithstanding. Please participate in Tumblr Labs only as directed.
