My only concern is whether Google shall drop me for going too fast?
This is speculation, but I would assume that Google is aware of social media traffic and, if need be, could correlate it with link growth. If your inbound links start growing faster than traffic to your site would warrant, then Google might be inclined to look upon those links suspiciously.
Additionally, as blog stories go off the front pages, links from them are likely to diminish in value. So it will help if you content is valuable enough over the long term to continue to attract inbounds.
But Google understands the kinds of linking blips that popular stories can bring, and likes links that come via "natural" promotion.
