Recurring downtime, transfer delays (which seems mainly to be solved now), and most importantly, lack of regular communication.

Goddamn it, and engine bugs that mean you're being robbed.  I am stunned that people aren't really furious about this!

It has been five days now, but they have finally acknowledged the report of sniping hole.  Not dealt with it.  Not responded to it.  Just an ACK.

Another user tells me he has found and privately reported a minor denial-of-service attack directly on the engine which looks real to me.  Again, that report has been acknowledged.  I think I will publicise it if he doesn't get a response back in a reasonable amount of time.

if you're only trading by watching BitcoinWisdom and others, I see things happen as much as 18s ahead of you.

So if you are not trading looking at the undocumented API you are beign ripped off by those who do. Very nice feauture!

Bitcoinity have started using the stream since I made that post.  BitcoinWisdom are at least aware of it, perhaps even using it by now.  Clark's rtbtc has used it for a while.  The Reddit post has partly solved the lack of documentation of the stream; the bigger issue here is the sniping window.  It seems it's being actively exploited now too.

Re: Brainwallet Passphrase limits?

Don't.  Bad for privacy, usually done wrong and hacked, even if done right people often forget or lose the password...

If you still must create a brainwallet, for the love of $deity_or_lack_thereof please make sure you generate the passphrase genuinely randomly - e.g. an Electrum-esque 12 Diceware words chosen with real dice, written down multiple somewheres (perhaps split up) - and use some kind of KDF that requires a substantial amount of time to slow down brute-forcers anyway. 

But, please, just don't even do it in the first place.

A little unfair if my bitcoins have to compete with a bank ...

Not really, since your Bitcoins already do.

I'm genuinely stunned by how shamelessly unattractive and dishonest that proposition is; it's openly a method to force negative interest rates on you:

Quote
Right now, your $100 bill is equal to the $100 in the bank. If you're bank account has a 5% interest rate, you earn $5 of interest in a year and that $100 bill is still worth $100. But what would happen if that interest were -5%? Then you would lose $5 over the course of the year. Knowing this, you would rationally withdraw the $100 ahead of time and keep it out of the bank.

...

"You have to do something a little bit more to get the negative rate on the paper currency," Kimball said. "You have to have the $100 bill be worth $95 a year later in order to have a -5% interest rate.

...

Got that? After a year of a -5% interest rate, $100 dollars are equal to $95 e-dollars. This ensures that paper currency also faces a negative interest rate as well and eliminates the incentive for savers to hoard dollar bills if the Fed implements a negative rate. Presto!

Something tells me you'll be much happier with your (currently mildly inflationary, but soon) static/deflationary Bitcoins.

Re: Newbie Bitcoin Wallet Address Questions

First question - is it safe to give out the wallet addresses like I see in signature lines here and used for the purposes of drawings and donations?

Does this put the security of said wallet/bitcoin address in jeopardy?

Reusing addresses puts the privacy of you (lots) and everyone else (a bit, because everyone you send to/receive from is now linked to you whether they like it or not) in jeopardy.  Don't put one in your sig.  Make a fresh one every time.
