    Dear SpiderOak staff
    Is there any justification for this kind of posts—i.e., on GIMP and other miscellanea—from a *file sync* firm? I've subscribed to the feed to keep up-to-date with SpiderOak developments and releases, but much of the posts I receive feel disturbingly like marketing spam.

    Hy all!

    Thanks for sharing your thoughts. We thought we'd invite guests bloggers to fill in the gaps with interesting and fun posts. But don't you worry – we have exciting SpiderOak announcements and news planned as well. :-)
