This is called pronoun dropping [1] and happens in quite a few languages, including Japanese as noted.
I had a friend in college who would always point it out (in English, where it's not very common). I still notice it often years later and I'm pretty sure it's thanks to her making me aware of it.

Interesting. The Chinese examples on the wiki page sounded completely natural to me and are in accordance with how I speak/interpret the language, but I never realized I was dropping pronouns due to their inference.
Thanks for the insight!
"I have used PHP for years." The first sentence establishes the subject is "I".
"Like it." etc Because this sentence doesn't have an explicit subject, it is implicitly the same one, "I".
As I recall, "wa" and "ga" were the Japanese particles which established new subjects. Say you wanted to talk about Bob's new car, you'd say something akin to "About Bob's new car, is expensive. Arrived last week. Has poor gas economy."
