Whilst I'm glad she's gone as she's clearly been out of her depth since becoming PM, I fear it'll be a case of out of the frying pan and into the fire with her replacement. I really hope this doesn't end up with a no deal Brexit, which I think will be an absolute disaster.

If they couldnt figour out anything in 3years time.... then what are they going to do with another 4months?
Honestly EU has to draw the line somewhere, I doubt it ll be extended again.

Its gonna end in a No deal, because non of the parties are willing to compremise, or set country before party politics.
Ireland will get a hard boarder too, if a No deal, goes through.
UK is about to break the "good friday agreement" by how messily they handled this "brexit".

As a Belgian, I kind of have respect for May. She became PM in arguably the worst situation imaginable, survived for much longer then anticipated and left a position open nobody save for a few unlucky opportunists will want to fill.
With the EU being as hard on the UK as it is and the UK as divided as it is, no one will easily solve this crisis.

Please let Boris Johnson be PM!
Please let Boris Johnson be PM!
Please let Boris Johnson be PM!

There will be a massive grassroots backlash if he is not on the ballot. The party might as well give him one by default. 

EU already looks ridiculous, giving into the UK time and time again with extensions.
I actually think this is the last one, if by Oct the UK hasnt figoured things out, they will crash out then.

WTO rules, Hard Boarder/customs on Ireland, ect.

Damn I'll almost miss her. She made the political gridlock in Washington seem almost not as bad. I swear she has come off as one of the most ineffective leaders since... well Trump.

The EU giving in is very much self serving. The EU doesn't want to leave. Extending will lead to either a better deal for the EU or a canceling of Brexit. EU would be stupid to force a hard Brexit. It's ironic how the EU cares more about UK citizens than the UK.

There's something appropriate about Brexit being scheduled for Halloween.

Brexiteers, in my observation, have had two motivations in connection to the departure policy: a desire for reduced immigration and a desire for foreign trade policies more favorable to the British (...okay, English) workers. Setting aside the moral issue I take with the former goal to focus on the latter, the stupidity of Brexit is that it will have the exact opposite real-world impact, and we have already seen as much quite clearly in the harsh terms that both the Trump Administration here in the U.S. and also Xi Jinping's government in China have demanded upon the UK vis-a-vis any new, post-Brexit trading deal that may be reached (example). What the tougher stances of the U.S. and China toward the UK in this new atmosphere demonstrate is the reality that leaving the European Union means that the UK will have MUCH LESS bargaining power in the future, NOT more! The UK will emerge from this process much weaker, not stronger. That is why Brexit, and especially a hard Brexit, has been the policy most favored and advanced by Russian intelligence.

And the millionaires, as there's the fraction of Brexiteers who wants to turn the UK into a giant tax haven for themselves. But since that's not possible anymore under the EU (Luxembourgs and even Switzerlands (due to bilateral contracts with the EU) Banking secret for instance is almost gone), they choose to leave.
