Twitter is great with a mass appeal. Sometimes it can be somewhat silly with an incredibly wide range of comments, pictures and videos being "tweeted" constantly. There are, however, many much smaller, subject specific micro social networks that work somewhat similar to twitter but on a much smaller scale. Here are some good Twitter Alternatives as well as Alternatives to Twitter
Stock Twits -Stock Twits , as the name suggests, is all about stocks and financial markets. Folks there "twit" rather than "tweet" information about current trends in the stock market. What is hot. What is Not. Instead of # (hashtags), the $ symbol is used in front of the symbol that represents a companies stock. ie. a Twit starting with $TWTR would be about the Twitter stock. One might think this would be a boring social network but to the contrary. Things get heated up in there, sometimes even more so than I have ever seen on other social media platforms. Try it now!
Snapsext - Snapsext is a social network for adults who like to chat about adult things, share adult pictures, and video chat live while showing adult things, and eventually ending up in someone's bedroom for some adult fun. If that is your type of thing I highly suggest you check it out. Try it now!
Tumblr -Tumblr has a little bit for everyone. Blogging, commenting, discusions, a lot of pictures all grouped together in this eclectic community. It is pretty much a combination of Facebook, Twitter, and Instagram all built into one big platform. Try it now!
