Looks like an interesting project! How do you feel about rolling out your own coin, instead of relying on the Ethereum network for token distribution? I certainly won't invest if it's an Ethereum token, because there are way too many of them already, and I don't like Ethereum.
I think if there is your own coin on the blockchain, this can also be used as an incentive payment method for content creators later, so you'll need your own blockchain+coin anyway. Why not distribute those coins in an ICO right away to the ICO investors?
Also please consider switching to Slack or Discord, not everybody has a mobile phone to join the Telegram platform. Slack and Discord also work on mobile, but don't require a phone number.
"Selling pressure", as you are noting it in your whitepaper, certainly won't be a problem if you make a PoS coin with 5% per year, for example. It is an incentive for people to run nodes on the network, which in turn could also be used for CDN functionality etc.
