Popular Mac punditry figure, developer and publisher Marco Arment
has announced that he has sold a majority share of his web-article saving and syncing app Instapaper to Digg owners Betaworks
. Under the deal, Betaworks will "take over the operations, expand its staff and develop it further," says Arment, while he will continue advising the project "indefinitely." He admitted in the blog post
that he had "had trouble" keeping up with the needs of the service for the past year, while rivals such as Pocket
could devote more resources.
