Tipping supplements service worker salaries (bartenders, servers, baristas, musicians, etc.) offline, why not extend to offer as a monetization option online?
Tipping gives people the power to chose how much and how often to support people. Rather than automatically distributing a fixed or limited amount at a certain interval, you open up the possibility for ad-hoc discrete payments.
Tipalink.com provides a service that extends tipping from the creator to creator’s content. Tips can be received on the web address, or “link”, of a web page - which may contain an article, a project, artwork, etc. Some may give nothing (most already do this), some may give $1 per article per month, some “big tippers” and enthusiastic supporters might drop considerably more and/or more often.
