If you are ever unsure whether that trend has actually changed or if it is maybe just a market bounce, take a look at Google Trends and see if there are actually more people interested, or just the same money as before moving around differently.
It's also important to remember that it isn't required for the Google Trend graph to rise for there to be fresh interest in Bitcoin. It's not often that an old Bitcoiner types "Bitcoin" to Google so it's safe to say that as long as the trend doesn't go to 0 there is continuous new interest in Bitcoin.
Right now the trend indicator has reached a fairly stable level after declining from peak hype levels. It's still on relatively healthly levels meaning there is a lot of new interest every day. I expect there to be a slow growth in trend levels in the future, based more on actual development, less on pure hype.
There are some other indicators that seem to indicate that we have reached a bottom at this time:

http://www.blockchain.info/charts/cost-per-transactionI have a hard time seeing it going anywhere but up from this point on, unless something radically negative happens. Although I do think that the growth will be different this time. I certainly hope it is, we don't really need a price increase that's 99% based on speculation. That doesn't help Bitcoin much because it will again lead to a massive decline. And it will take volatility through the roof again as well.
Personally I'm hoping the early adopters (those who haven't lost their coins) do the right thing when Bitcoin starts growing faster than it should. I hope they understand that when the speculative demand spikes, they should counter it by selling massively. If the big holders decided to sell big when the speculative demand is spiking and then hold when demand declines, that would keep price volatility in decent levels and it would help to circulate those coins.
It is puzzling that a lot of the early coins haven't moved regardless of price which means that most likely a high percentage of early coins have been lost. So maybe there are not as many active early adopters as some think. Maybe it's the speculators that hold all the cards these days, not the early adopters.
