Blogging has become very popular over the last few years as a great way to share almost anything that you want. Tumblr have been one of the biggest reasons for this increase in the popularity of blogs as they have made it very easy for anybody that wants one to have their own blog.
Tumblr is a microblogging website that allows people to put up almost anything that they want on their site. It differs from a traditional blog in a couple of ways. The first is that most of the posts that are put up are much shorter than they would be on other blogs. Often they are just a few sentences or even just a picture. Of course this does not mean that you can't put up a longer post if you want and use it as more of a traditional blog. That being said the main reason that most people use it is because it allows them to make such short posts.
The other reason that Tumblr is different than most other blogs is that it does not require you to have your own domain or to have to deal with any of the technical side of things. Admittedly there are quite a few others sites like this but none are nearly as popular as Tumblr. The reason that this is so useful should be obvious as it removes the need to have any technical skills so you can just post what you want without having to worry about it.
One other reason that Tumblr is such a useful place to have a blog is that it has its own community of visitors. One of the biggest challenges that most bloggers face is getting people to visit their blog. The most common way to do this is by getting them through the search engines and this is something that you can do with Tumblr just as well as with any other blog. However because there are millions of people who use Tumblr you can get traffic directly from those visitors as well. In fact there are lots of very successful blogs that get all of their traffic directly from Tumblr.
While there are clearly advantages to using Tumblr there are also a few disadvantages that you have to keep in mind. The biggest of these is that you do not actually own the site. This means that you are subject to terms and conditions that Tumblr puts on the use of their site. In general these are not to onerous, particularly when compared to other blogging sites but you do have to be aware of the rules. That being said as long as you are not doing anything that is a serious violation of policy you should not run into any big problems with using their site.
