Would be much-much better, if you post all clients/wallets 5-10 minutes before first genesis block starts. This will made impossible to have a distinct advantage of you as a creator and all your group of friends. Because if you start genesis block and write a message with links to wallets/clients - when others prepare their systems to mine you and your company will dig as a crazys because of no competitors to you.
Another important detail to others - is peer/nodes distribution. As i seen on all previous coins for that week - first nnnnn blocks are hard to mine by community because of lags, even that peoples have a very large hashpower. Starting blocks and difficulty makes huge hashpower useless against lags. So you need to start nodes all around the world to be the honest (i suppose that downloaded and started wallets in prepare-mode will be enough to make net of distributed peers).
First - give others mining instruments/clients, second - give others the opportunity to compete in equal conditions, third - launch genesis block.
Then your coin can be successful. In opposite - this coin will be as others dump&pump&die-coins.
Good luck.
PS: i think i will be out of competition because of other side of planet and too big pings (55-300ms). It's fatal.
