Active development on Google Wave, a collaboration tool that used features of email, chat and document sharing, has been shut down. Google announced that the chief reason for discontinuing Wave was the low user adoption. The platform will live on within other Google projects, as well as the many portions of Wave that have been open sourced.
Sustaining an effective engagement campaign can take a surprising amount of work. You could limit yourself to following the leads from the data you collect, but following without interacting first will get you a very low follow-back ratio. More importantly, if you follow and then forget people, they may follow back, but they’ll soon forget you. A high number of followers who don’t reply to, mention or retweet your account are of no value. True engagement is long-term and repetitive.
