While I have heard this many times, and have used Intersango, and understand that they have the respect of well respected members of the community, I have serious concern about
- 1) their repeated discovery of other exchanges security flaws
combined with
- 2) the manner in which they bring this (apparently) to the public attention before alerting their competitor that they have been engaged in #1.

This is one of the first things I saw online about Intersango (in fact it was BTC-e's response to the blog post about their security flaw they sounded pissed). I have seen this at least one other time, very recently.

While this may be completely benevolent, and performed as a service to the community, it raises some red flags. Are they trying to discredit competition? Are they trying to break in? If so, why, and would my information be safe with them?

These are the types of questions that one must ask when one competitor repeatedly discovers security flaws in others. Each repetition makes the behavior more suspect.

As I would like to have an additional exchange that I truly trust, and as there seems to be some relationship (at least in overlapping people) with the GLBSE, I would like to find out the whole story here, so that I might be able to trust Intersango. (because, despite the above, they still seem to have the best rep here!)
