What need and what is the advantage?
LinkedIn - a social network for marketing, job search and recruiting . The user profile can be built into a kind of extensive detail of employment and in fact constitutes a substitute for the resume document. During use, many contacts can be established with relevant stakeholders.
Until my encounter with the network was poor, I will now adopt the use of the tool to search for work in greater depth and through the creation of connections.
googleKeep - An application where you can manage a list (a kind of "check list") that is updated in real time by everyone who is a partner with it. Many people manage their daily lives and tasks with help lists. Whether they are written in a diary, notebook, or smartphone. Managing lists in an app is convenient because you can share with other people (for example, office tasks, apartment shopping lists) and anyone can add an entry whenever they want. You can also open the list on your computer.
Since I often use a certain interpretation to manage such lists, I think it would be more convenient to switch to googleKeep because I will have the option to share with friends if I need them in the future and are linked to the Google Account so I can access them not from my smartphone.
