2014 - LinkedIn premium profiles will look like Facebook to defeate Viadeo

Professional social network LinkedIn invented another reason to entice more people to sign up for its paid, premium version: profile design with bigger pictures, additional features to be more easily found and contacted and expanded data on how people are viewing you. We may say it looks like Facebook, but LinkedIn says it’s simply about making a better connection: the changes will help premium users stand out more in search results as well as reflect a “more personal feel,” according to the company. While the new Profile look will be available only to premium users, all members will eventually get a version of a new profile that will let them use bigger pictures in the backgrounds of their profiles.

2012 - What is the professional social network #2 after LinkedIn? to fight Viadeo

If we wake you up in the middle of the night and ask what is the most popular business-oriented social network in the world, you'll probably say that LinkedIn. But if we ask you what is the professional network #2, you'll either shrug your shoulders or say "who cares? anyway we have Facebook for that". However, there are two networks that call themselves "# 2 after the LinkedIn" and the first of them is BranchOut, that is nothing but an application for Facebook. It has 25 million registered users (compare with LinkedIn - 150 million). BranchOut allows you to create your professional profile on top of the common profile on Facebook. It will be accessible for all who also installed the BranchOut app. In general BranchOut copies the basic functions of LinkedIn for searching and establishing business relationships, but also lets to combine professional information with personal. In some cases - it's useful.

The second LinkedIn competitor is Viadeo. It's more popular in Europe and China and has 45 million registered users. The main feature of this network - is its regional adaptation. Unlike LinkedIn, which is the same in all countries (only allows to change the interface language), Viadeo is trying to find an individual approach to each region. It's founders say that different countries have different traditions of business communications. By the way, recently Viadeo raised $32 mln and entered the Russian market to become the major player there.
