To much to write here, but I'll try to name few: - NAME - easy to remember, good domain, suggestive accordingly with your intentions. - UI/UX - to be attractive and same time simple but functional, adaptive and responsive to user's needs. - CLARITY - in this way the users to understood in few clicks how it works and what could take advantages from your network. - CUSTOMIZATION - to give the users a relative control over the interface and modules (to change the theme, to drag the modules in different places, to add/remove modules, etc). - CLOUD PROVIDER - a good provider which to offer scalability and speed - SPACE (optional but already become a must) - to provide to your customers cloud storage which to integrates with the main functionality of your network. - COMPARTMENTALIZATION - as to provide users the possibility to create groups(circles/tribes/etc), to assign different functions to groups/files, to create behavioral rules for files/actions/etc Depends on you how complex want/need this network to be. If you consider I could help you draft the architecture of this network, you may reach me at bogdins at gmail dot com or by skype at technobogdins.

Yes and no! While Facebook is more flexible and its users are more likely to respond to your direct approach, on Linked In is more difficult. From my experience, on Linked In is more lucrative to share your problem/issue in a form of a question with details on group's board, where the dynamics of Q&A is much better. Of course you could address your connections directly or by an email campaign, just don't be aggressive with the approach. Most important (and the determinant for your addressing way and channel) is your product/service that you offer.

You should remain focused on what you do best. Have a broad approach on different markets/requirements from your clients (current and to come) and same time have few employees specialized in the most demanded fields. As a general rule, a professional which provide results in a mixed environment is to be preferred to one which excels in just one field. Is about adaptability and the ability to get the things done in the way to produce results. There is another issue: could happen to design a campaign which you know for sure that will produce results, but your client to dislike it. If the client is big is difficult to convince about your opinion. Bottom line, work on a wide spectrum and have few collaborators specialized in niche markets - even just for ideas and insights. Another useful approach is to design several drafts for a campaign, which to be as simple as possible, only to show the direction and reaction of your client, and to refine that one which have the biggest chances to balance your gut and clients desire.
