Again, I know it's still early, but I was expecting a little more carbonation than it had. It was basically what most people would consider to be a flat beer.
After doing a little research, I'm now extremely confident that it'll improve. Clearly, I still have a lot to learn about this. :)
Some are saying that it could take at least 3 weeks for decent carbonation to develop. In some cases, even longer.
The rule of thumb seems to be: if it's not carbonated enough, let it sit for another week or two. Patience and time will fix low carbonation.
There's a good forum message here, along with a time-lapse video of how a beer changes as it ages: http://www.homebrewtalk.com/f35/bottling-tips-homebrewer-94812/#post1030387
As some suggest, check it every week, take notes, and compare how it improves over time. That's what I'll be doing.
