As for store hack the reason is the number of subscriptions that thread has. As soon as you click submit to send a reply, vb needs to send many mails to many people and it can be a bottleneck if number of subribers are too much or mail server is slow to respond. In extreme cases you (ie poster) may even experience timeout errors if the script can not finish the process in 30 seconds which is default timeout duration for PHP scripts.

I'm hoping that VB3 will break down this bottleneck with a wiser subscription mailing algorithm. I don't know how they handled it as we don't have the code yet but the concept of daily/weekly notifications gives me hint that notification mails are handled more wisely in VB3. I hope devs included the algorithm that will send even instant notifications in smaller pieces and in time when they are more than X in a crowded thread. Since vb.com also has highly participated threads (like new release announcement threads) I'm sure devs are aware of this issue anyway..
