“Despite – or maybe even because of – that
nebulousness, SharePoint is a brilliant success, for a couple of
reasons. In a way, it’s Microsoft’s answer to GNU/Linux: cheap and
simple enough for departments to install without needing to ask
permission, it has proliferated almost unnoticed through
enterprises to such an extent that last year SharePoint Sales were
$1.3 billion.“But as well as being one of Microsoft’s few new billion-dollar
hits, it has one other key characteristic, hinted at in the
Wikipedia entry above: it offers an effortless way for people to
put content in to the system, but makes it very hard to get it out
because of its proprietary lock-in.”
