One of the biggest mistakes retailers make is to open up accounts on every social media platform they think is relevant and then leave them alone with no activity. Having an account with any of the social media platforms does not mean your business is into social media any more than owning golf clubs makes you ready for the PGA. In fact, social media users are turned off by the retailer who opens accounts and does not engage with clients and the public and consequently become labeled a pretender.

Most of what I'm going to list involves sharing sponsored links, although you'll find a few other oddball things in there, too. But sharing sponsored links is where it's at because big brands want to get themselves out there to as many people as possible, and they know people are on social media all.day.long. So yes, they are willing to pay you to help them get their brand/product/message across.

Managing social media isn’t a particularly lucrative profession yet, but it does serve a growing need for a lot of businesses. If you keep an eye out for job postings you might be able to nab a job promoting a company or brand on various social media services. A lot of those jobs are independent contractor positions, many of which you can work remotely. If you’ve got a lot of experience with social media beyond just being a user, though, you may be able to get hired to develop social media strategy. Telling businesses how specifically to approach their social media presence would very likely net you a nice income.
Usenet, which arrived in 1979, was beat by a precursor of the electronic bulletin board system (BBS) known as Community Memory in 1973. True electronic bulletin board systems arrived with the Computer Bulletin Board System in Chicago, which first came online on 16 February 1978. Before long, most major cities had more than one BBS running on TRS-80, Apple II, Atari, IBM PC, Commodore 64, Sinclair, and similar personal computers. The IBM PC was introduced in 1981, and subsequent models of both Mac computers and PCs were used throughout the 1980s. Multiple modems, followed by specialized telecommunication hardware, allowed many users to be online simultaneously. Compuserve, Prodigy and AOL were three of the largest BBS companies and were the first to migrate to the Internet in the 1990s. Between the mid-1980s and the mid-1990s, BBSes numbered in the tens of thousands in North America alone.[11] Message forums (a specific structure of social media) arose with the BBS phenomenon throughout the 1980s and early 1990s. When the Internet proliferated in the mid-1990s, message forums migrated online, becoming Internet forums, primarily due to cheaper per-person access as well as the ability to handle far more people simultaneously than telco modem banks.
