&quot;Develop a great little application&#x2F;product that pulls you in and develops a decent user base only to have it disappear&quot;<p>The worst part is when they do this with acquisitions (which Picasa was, though admittedly it was acquired quite a long time ago).<p>Also, even when they don&#x27;t outright kill apps&#x2F;services, it is painful when they basically let them wither on the vine (see: Google Voice, another acquisition of a promising product that Google snapped up and then basically put into hibernation soon after).
