Santa Monica-based DocStoc, the online document sharing site run by Jason Nazar, just released a new feature Thursday afternoon, DocStoc Collections, which allows users to create their own groupings of documents by topic. The new feature so far includes collections such as "Starting A Small Business," "Traveling On A Budget," "Writing Better Cover Letters," and similar topics. Nazar told socalTECH that the new feature was released so that the site could provide the "best quality experience when looking for documents." The new feature follows a major update by the firm last week, which saw the company exit beta and add revenue share and a major home page redesign. DocStoc is venture backed by Rustic Canyon Partners.
