rhetorical question - but anyone who has used both Mt Gox and Intersango can see Inter have a long way to go to promote themselves to new traders - community loyalty will surely run dry soon, if they don't sort out their funding issues. I've had £650 stuck in limbo for over 10 days now, with no sign of resolution. Someone set up a UK competitor please...
I know what you mean; I've got a lot of affection for Intersango having used them since the early britcoin days (despite being bitten by an early trade matching bug). However, they have completely ignored many of the suggestions I've made to them for site improvements and the site still feels like something from the 2000s. The one they did take (market maker bonus) seems to have reduced the spread (as one would expect), so I don't really see why they're so against the others. Instead, I got a long email telling me that their unique selling point is that they're so reliable and trustworthy (that's a bare minimum requirement for an exchange guys, not a unique selling point).
Here are some ideas again in case Intersango are listening:
Why is the site hard coded so wide (try using it on a mobile for some fun, or even just a half-width browser window)? Where is the AJAX? Where is the live orderbook display? Where are the stop loss orders? Why are there two/three different pages needed to manage my outstanding orders (competing over a penny difference with someone at the top of the orderbook is immensely frustrating)? Why is it damned near impossible to place a market order for 100% of the GBP I have? Why do I have to get a calculator out to buy £50 worth of coins when I'm sat in front of a 2 GHz PC? If I were being really brutal I would ask why Intersango can't automatically proxy out to Mt.Gox (like bitconica does) to get a bit of volume on their own books? If I can arbitrage between exchanges, why can't the exchanges do that themselves automatically -- get a bit of peer-to-peer goodness going on?
It's frustrating because they obviously have some talented developers working for them; and they've gone a huge distance to jump from britcoin to intersango but now seems to be sitting stagnating. If bitcoinica can leapfrog them in such a short time, it shows that it can be done if you supply the market a unique feature that other exchanges aren't -- get implementing features then, who knows which one will be the "killer app" (if I had to guess, I'd say stop loss would tempt a lot of people)?
There are plenty of features that Mt.Gox is missing too of course, but being #1 usually means you can rest on your laurels for a while.
