Ask HN: Writing your bio

I go back and forth on this one a lot. How do you address past projects in bios. Just talk broadly about the experience ('x' years of experience in widgetmaking) or more specifically (built didrigidoo.com, happyducks.com and something else)? Between personal sites and LinkedIn, always struggle with this topic and wanted to see what others do to balance the line between being clear about your experience, without being too over the top about it.
