At least for Xmarks, the post-mortem seems to have spurred a turnaround. The pledge drive mentioned in the article has been set aside pending a 100% purchase:

> I’m pleased to announce that we’re in the final stages of completing a sale of Xmarks to a new owner who is 100% committed to keep our great browser sync service running smoothly.

(A truly fantastic and indispensable service, allowing you to use any browser at any time and have all the native bookmarks synced across browsers and OSes. I am one of many who wouldn't mind paying a fee somewhere between Pinboard.in and Evernote.)

Ouch... I don't know what to do. I've been going so long it seems normal to me that my startup is ugly and crappy. I'm a single founder, I procrastinate a bunch, and I had to get an outside job to pay my patent lawyers. I regularly go weeks without doing anything at all on my business because of all the other pressures on me. I started in 2004 and I still haven't launched. I keep thinking about how much better my stuff will be than anything that has existed so far, but man I get discouraged.

I have quit multiple times, but somehow I don't think I could go on without the hope that one of my businesses will someday thrive. I try working on other things, but I always come back to this one business idea that I believe with all my being to be a good idea if I can just get it going.
