I personally think that the low price is an opportunity to buy, as you said (asked, haha). And I - a fellow minnow - am buying. The lowering price of late just means that many of the short-term investors who were attracted here only for financial reasons have been selling/dumping to make a quick profit - and there's nothing wrong with that.
There's many of us here as bloggers and who just like it as a social network (opposed to a way to turn $100K into $125K or $1000K "overnight") and more will continue to come regardless of price. Like you I'm here for the long haul I believe, and we will all see the price rise and fall over the years together, and maybe swap stories about if/when we bought, or should have, but will still be here in the same way people still use Facebook. I'm 99% certain the price doesn't affect whether the site continues to exist or not. But with all the apps and spin-off Steem projects that keep coming out almost every day and the massive growth the platform is experiencing, I'm also 99% sure that one day $5 Steem will look ridiculously cheap to people down the road.
