I 'll add my experience with asyncio and twisted:

1) debugging is way better in asyncio, with ipdb you can step in co-routine. In twisted, you will end up somewhere in internals.

2) asyncio is end of unhanded error in deferred :) (or you need to remember to add addErrback everywhere, even after addColbecks and addBoth)

3) with trial testing is frustrating, sometimes error raised in wrong test because of global event loop (for instance you forgot to mock external call). In asyncio world loop passed explicitly and this is good for testing.

asyncio is just nice API for async programing and event loop management. You should start from something high level in order to obtain asyncio ideas, like scraping [1] or try web development with aiohttp [2]. And then if you want to write some library or port database driver, look for examples at aio-libs[3] github organization.

I think problem is more deep, I do not want to make other Conspiracy Theory but here some story from other huge Russian social network (vk 150m. users). There is one small, not that big group (like fb groups), users made agreement, that no one will post next day (something like honeypot), and those who post would be considered as bot and baned forever. So next day couple or so bots generated comments encouraging others do not go on strike against some political party [0].

I do not know is it applies to FB, but those who have like 100k bots have some power too.

I think reasons is pretty strait forward:

[1] You can win a bunch of contests, competitions like those who have lot of likes can win iphone or other tech.

[2] You can sell likes.. just google and you will see, there are alot of places where you can buy it.

[3] Manipulation of public opinion.

Edit:

From FB side:

[1] they still have growth of users

[2] more bots == more clicks, more likes more FB value "on paper", more revenue

[3] and when they stabilize their market value they can easily kill those bots, just require them activation by phone.

vk.com Russian social network, had same issues, but they enabled phone activation for averybody and its not that easy to buy a lot of phone numbers in Russia, but some hackers just pay to vk.com admins...

FB does not need do that shady stuff. Here some facts.

[1] Bot registration on FB is really easy. If you try register 100 fake users in direct way you need to deal with javascript and web forms with strange ids, cookies and so on in your script. But if you enter fb.com without enabled javascript, they ask you change browser or use mobile version, which is not require* js at all.

[2] You can register number of accounts from one ip without CAPTCHA

[3] Only one "difficulty" is to find batch of emails, it is not that big issue since we have services like mailinator.com.

So 15 -25 loc script on python do all your job. It is not required use any tools like selenium or special skills , only basic understanding how http get/post works.

Why fb doing all this super easy bot registration stuff? I think we all know why.

Edit: spelling. Sorry non native English speaker here

Painting is called Reply of the Zaporozhian Cossacks to Sultan Mehmed IV of the Ottoman Empire, by the way [0]...

Original reply was: Thou art a turkish imp, the damned devil's brother and friend, and a secretary to Lucifer himself. What the devil kind of knight art thou that cannot slay a hedgehog with your naked ass? The devil shits, and your army eats. Thou son of a bitch wilt not ever make subjects of Christian sons; we have no fear of your army, by land and by sea we will battle with thee, fuck thy mother. )))

Yep, its must be as awesome as Simulink. But in most real world examples you should use more basic programming languages in order to feel all process (handle discretization or numerical integration manually). In Simulink you connect couple block and thats it... everything important are hidden behind the scene.
