Почему заглох Google wave

Сам он в любом случае работает, но вот популярности он не обрел.

Эрик Шмидт пояснил после объявления о закрытии Волны, что, увы, бывают с их продуктами неудачи (но технологии применяются в других продуктах):
Speaking at Techonomy, a technology conference in Lake Tahoe, California, Google chief executive Eric Schmidt said it was hard to say why Wave did not strike a chord with a majority of users.
"It's a very clever product. You never know why it didn't work".
"Our policy is we try things. Remember we celebrate our failure. This is a company where it is okay to try something that is very hard and not have it be successful."
Mr Schmidt said that Google will take what it has learned and apply it to something new. He refused to be drawn on what products the technology will be used in.
Many people who tried Wave complained that it was too hard to use or that they did not understand why they would use it.[1]
