I like it a lot because it gives me a complete information about a specific topic and in the same way I can interact with other users who want to share this information. With just one click I can go "pinning" images organized by boards; And follow in a fast way images that interest me, follow thematic and share it with my contacts. It contains a huge variety of information which helps me explore new things, ideas and projects.
Well basically the only thing I do not like is to register in this social network, you have to be invited and usually the invitation takes time to arrive. The rest is great and very useful.
I invite you to uniter pinterest and I encourage you to follow the people you are interested in interacting with (friends, clients, professional colleagues). At first I know it seems complicated by its difference to other social networks but it is a very simple and intuitive application that does not require much knowledge to use it. Great to motivate your daily learning.
It gives me the benefit of keeping up to date on designs, projects, ideas, etc; More than everything I use for that in question of work. Personally, it contributes to my knowledge, expands my creativity and expands my network of friends. It's great to meet people with whom you have common tastes.
