Have you used Bitdaytrade much, Meni? Is it stable?
I've used it a bit. There were a few bugs that needed fixing but it's working fine. Some more testing, as well as an external security review, will need to be done before it can be considered stable. Until then Alberto will limit activity (by restricting access to the more popular BTC/USD trading and/or limiting the size of positions) to keep any flaws that might turn up on a manageable scale.
Up to 1,000 bond will be put up for pre-IPO sale. They will be sold at a 5% discount for 0.95 BTC each. This is only available to investors buying at least 100 bonds. Send me a PM to reserve your spot.
What is the purpose of a discount like this?
It helps assess and build up demand, and gives earlier surety that at least a minimal number of bonds will be sold. It also gives an opportunity to be in touch with some of the more dedicated investors. It's not essential to do this, but it's fairly popular here and there's no real reason not to.
