I had totally forgotten about that post. I am happy to report that my basil plant is still alive and kicking. The yield isn't what I'd term abundant, but it has gotten us through a few pinches. I've even had to prune its flowers on a few occasions, and it's looking like a strong candidate for a re-pot in the near future.
I had the same problem with bugs until I took two actions. First, I separated it a few feet from a nearby spider plant. I was told by someone that this particular neighbor is known to house tiny insects. They apparently enjoyed getting out of the house for lunch, so to speak. Secondly, I mist the leaves with either slightly soapy water or even windex (a very, very light mist) whenever I notice insects camping out there.
My basil's toughest times were the result of my watering and feeding experiments. I have learned to recognize that if the leaves turn very pale green or even yellow, I'm probably watering too much and also that if the leaves are sparse or under-sized, it's time for a few drops of plant food.
The final advice I can give for basil is make sure your window has plenty of light. My plant has never been outside, but it has thrived in a well-lit window even in winter.
This year, I may expand to some other herbs.
EDIT: I should note that this plant was purchased alive and potted from the Armitage farmer's market last June for $3. It has produced for me much more than $3 worth of basil (at Treasure Island prices).
