Hi,
I've been listening to JapanesePod101 for years, ever since podcast one.
You really do a great job, and I've learned a lot of very helpful Japanese from you. There's just one (okay two) tiiiiny thing(s).
The intro music and initial greeting just seems unnecessarily long. Am I the only one who feels this way? Sometimes it's a minute and a half before we get into the lesson. I mean, I jump ahead to listen, but I wonder why there's such a long intro. Just sayin.
The other small point is that sometimes you use too much English. A word will be introduced in Japanese, and then only repeated once (or not at all), while 2 minutes are spent explaining it in English. I have to rewind just to remember what word we're talking about. It's fine to explain it, but repeat the word in the explanations, please.
Other than those small points, I think your podcasts have really gotten better and better. Thanks for doing such a good job.
