Being a project manager for the building of a social network can be time consuming and stressful. You may have to come up with ideas for the social network, make sure the social network is being created according to what was wanted, and be the central person for employees to turn to during the creating process.
Coming up with ideas is probably the most difficult and most important part to being a project manager. Coming up with new innovative ideas for your social network is not the easiest thing to do, and even if you do it explaining how you want it to be implemented to other people can be just as difficult. Imagine coming up with a great new idea that can have your social network become one of the best there is, and then when you get to that meeting with your web developers they cannot understand a thing of what you want them to incorporate, this is something that can very well happen, which is why it is important for you to be able to express your thoughts in a organized manner that people can understand. An idea is worthless if those who will make the idea a reality cannot understand what it is so they can implement it.
Once the idea is thought of and the developers understand it however as project manager you should make sure everything is proceeding along according to plan. Sometimes developers may say they understand something but a minor detail may be missed which throws off what you had envisioned. If this is the case monitoring the project as it is worked on can save you time since you can fix problems as they arrive by perhaps giving a more detailed explanation of what was going on in your head at the time. In this way they can fix it and you will not find yourself with something you did not want once the network is up.
Sometimes you will also have to be the go between for different branches of people. If you are having different people do the web development and art for the site then you may have to be the person who relays messages between the two groups to make sure everyone is on the same page, there may also be times where you will have to answer questions about one group for another so that they may comprehend what is needed, so you should make sure you are familiar with both groups so that any problems or questions that may arrive can be answered quickly and effectively.
