There were only two posts in November! Everyday, I listen to podcasts, but don't write posts. There isn't time, and writing takes a lot of time.
I wouldn't have said 「ただ」 in that first sentence. I think it means something like "I was expecting more, but..." and usually implies that you are happy that it turned out to be less. Of course, this could all be just my misguided assumptions.私も忙しいし、コメントを書くのに時間がかかりますので、最近書いてません。すみませんでした。
