All we can ever share with each other are snapshots - points in time, bits of information - because plugging into someone and knowing their history takes time.
We can tell longer stories to bridge some of the gaps - but mostly we offer tidbits to each other. Over time, those bits add up to a bigger story.
You can't rush this. You can't dump who-you-are/what-the-project-is-about in one sitting. You can, however, offer cliffhanger endings and teasers so that folks will seek you out to continue the conversation.
Use your online bios, presentations, elevator speeches, grocery line up meetings... Leave a trail of bread crumbs about yourself as you gather the breadcrumbs of others.
