Just wanted to post this to help some people, I'm almost certain no one will ever look at it, but still,
Tip 1: Der, Die, and Das. (This tip is not my own, I saw it on this cool website called fluent in 3 months) 80% of the time you can figure out the article just by the end of the word Der endings, er, el, ling, ich, ig, her, ismus, or, us, eich, ant (And all dates) Die endings e, ie, heit, ei, in, ik, Keith, schaft, ung, try, ur, tion (And all plurals) Das endings Chen, o, lien, en, il, ma, tell, ment, nis um
Tip 2: German entertainment It's best to watch, German TV, YouTube, or something like that, and to read German books, not to mention I did manage to find a dub of the famous "asdf movie" YouTube series in German
Tip 3: Resources We live in a world where, with the click of a few buttons, we have the instant access to information, it's best to (in more ways than one) take advantage of it, there's a great YouTube channel, that although as if now is in a bit of a decline in terms of both views, subs, and in my personal opinion, content quality, called "GetGermanized" which has a lot of content about German culture, Daily life, and although not much, some videos on the language, a good channel about daily life in Germany would definitely be "Rewboss" and, there are others however those are (in my PERSONAL opinion) better than the rest and there's a lot more than YouTube resources, you just gotta look for em'
Tip 4: Try to meet someone you could have German conversations with to practice, and hopefully by the end of 2017 Duolingo will have made an internet version of chatbots so you won't have to
Tip 5: Don't stop at Duolingo, although I'm not quite sure, I'm pretty sure Duolingo will only teach you around 3400 words in their German course, that is definitely more than enough to hold a conversation, however that's B1 level, or rather a bit shy of B2 it's best to try and find ways to improve your vocabulary, because if you're like me and really want to get fluent you need C2.
Ok, these are just some personal tip's that work for me I wanted to share, I'm almost certain that either A no one will ever look at this, B a conversation like this already exists and I'm wasting my time or C both, and I'm going to admit that I just wrote this whole thing cause I'm bored and have got nothing else to do
There's this app I've found on Android (don't know if it's also on IOS) called DeutschLernen (one word, the icon is a German flag with a pair of headphones) which adds news stories almost every day, each story has an audio clip attached and a written version so you can also follow along. Most of them are around 3 to 4 minutes long so I personally listen to them when I am in the bus or something like but with years of clips you could probably spend hours with this app going through them.
The point you make about the wealth of resources we have online these days is something that should be taken note of.
When I started learning languages in the 90s it was so hard to get material in your target language. Often we had to make do with what was int he local library, or pay high prices for books and magazines at specialty stores. Now there is no real excuse not to learn, with the click of a button we can get limitless material in German over the net.
I just have two things to say: Erstens das Suffix heißt -Keit nicht -Keith. Ein Beispiel dafür ist: „die Ehrlichkeit“ — “honesty” Zweitens das Suffix: -Ich existiert nicht. -ig wie in „der König“ — “King”, ja aber vielleicht haben Sie das Suffix -isch gemeint? Wie zum Beispel: „alkoholisch“ —> „alcoholic” aber Achtung diese Endung betrifft Adjektive und nicht Nomen. “Ich” ist ein Personalpronomen. Viel Glück beim lernen :-)
