Mibbit: One year old, and profitable

The bandwidth usage before I did work on optimization was around 3TB transfer a month, which can cost.
BTW Thanks everyone on HN, especially those who contributed to my first post about Mibbit. It was harsh, and afterwards I almost gave up on the idea, but sometimes you need that kick.

It's actually quite nice being a lone founder... nothing that makes you more determined to succeed than being the underdog.
The other interesting stat I forgot to mention, is that Mibbit has about 3-4 times as many users online as Meebo Rooms at any point. I'm quite pleased about that, lots of room for growth though.
BTW, bandwidth shouldn't be expensive ($100 a terabyte is reasonable in the continental US) - it should be your time that's the biggest draw.
Judging by his stats, the website is still very small, hopefully for him, it will continue to grow. Congrats!
I'd be interested in stats on ad units and CTR (which I've always heard is really low on communication apps).
edit: Would also be interested in definition of profitability... Covering hardware/software costs? Covering costs PLUS able to eat ramen? Covering costs plus paying yourself a market salary?
The advertising revenue isn't massive yet, ($4 figures/month), but it's something to build on.
There's also obviously people willing to pay for chat/communication - campfire, liveperson type services.

These things are all relative of course, so it's big compared to lots of websites, small compared to the others :/
Enjoy the reverse burn rate & positive cash flow in 2009.
the rest: why not use mibbit or any other IRC client for #startups on freenode?
