Diigo fails to keep up with Firefox Rated 2 out of 5 stars

I have been a Diigo user for 4 or 5 years, and a paying subscriber for the last year. I am about to end that status, however, as I have grown weary of Diigo's failure to keep up with Firefox's disciplined, rapid delivery cycles, while apparently focusing all their time and attention on iPhone and Chrome apps. They appear to be an undisciplined, hyper ADD, juvenile bunch, more interested in appearing to keep up with the latest technologies than really doing so. Why else would they fail to implement HTML5 for their Firefox apps, and instead store data in prefs.js? Their toolbar apps bog Firefox and IE down to the point of suffocation. Their javascript only bookmark is ok, but there's no focus on improving it. So, I'd prefer to focus my attention and bookmarking activities at a site that has a more serious focus on user requirements. Next stop is my to terminate recurring payments to Diigo.
