japanese question

I've been learning Japanese for a short while, and I feel like I've been going about it the wrong way.

The shit I've been using is teaching me how to say shit, but I feel like it's building it on... zero foundation.

I mean, there's nothing wrong with knowing how to say KANKOO DESU KA or anything, but it's not teaching me grammar, what I'm actually saying (it just gives me a general English translation like "are you sightseeing?") or how to read or anything, and I feel like it's more of a gimmicky tourist version of Japanese. It's kind of like Rosetta Stone, I guess.

So, I've decided to ask you fellow basement dwellers. I found this particular blog

Should I follow this guy's lead? I've heard mixed things about Namasensei, I've heard about the Genki books but I don't really know shit about them, Rikaichan is a godsend from what I hear, and all that shit.

All his advice seems to be really good to me, so I figured I'd ask someone who actually knows how to speak it what your basic assessment is.

TL;DR should I follow this guys advice to into nihongo?

This is probably only advisable for someone who's quite experienced learning a foreign language.

Yes you may progress faster but you'll probably develop really bad habits. Lessons from a trained teacher who is also a native speaker would be best. You can tell the difference between someone who has been studied properly and someone who is "self taught". The former generally has a working understanding of the language and linguistics, and although it may have taken longer to gain natural sounding speech, they actually understand what they're saying.

Long story short, if you want to sound like a weeaboo who's in Japan to find his Kawaii waifu, then teach yourself. If you want to sound like an educated professional, get lessons.

That's not to say self study and research are not beneficial, but it would be like becoming an optometrist but without studying anatomy for any other part of the body. You may know how the eye works 100% but it's useless unless you understand its importance in relation to the rest of the body.
