My first testimonial is from... Joel Spolsky!

[appTranslator] looks like a very slick and smart solution to a common problem...
- Joel Spolsky

yessir !!! And I'll tell you what: I'm damn happy ! :-)

The story behind it was pretty stressing though. It all started on Saturday afternoon. Someone subscribed to my mailing list and wrote in the reference field of the form : 'joel on software blog'.

What ? Joel wrote about appTranslator ?? You can imagine how fast I rushed to joelonsoftware.com. Alas, nothing ! I made a site wide search and found no ref of appTranslator. From there on I didn't insist and opened Joel's Business of Software forum, which I hadn't visited for a couple of weeks. And there it was ! A post entitled 'App Translator - an interesting idea'. Suddenly things started to go bad. Really bad (at least in my mind). The OP was anonymous (I have no idea who it was). And a few people reacted negatively saying it was just a disguised ad.
Boy, I hate that: appTranslator is about to be known in the JoS sphere as a source of spam :-( VERY VERY BAD !!!
I immediately replied to the post to clarify the situation, but I was concerned it was not enough. I also e-mailed Joel and Eric Sink (since Eric is the official host of the forum) to tell them that, please, believe me, I'm not a spammer !
I must say that Joel rocks : In less than an hour, he replied to me, deleted the negative comments from the thread and added his own-follow up comment, raving about appTranslator ! Pffff.... Problem solved. The Master of Ceremony established the Truth and gave me His Blessing :-) I felt much better !

At this point, I must add that I had asked him for a link in a French translation of his articles that I made a couple of years ago. He declined but it looks like he gave a look to my product, which I hadn't asked.

The dang thing had stressed me so much (probably much more than it diserved) that it took me 2 hours to realize the value of this comment from Joel: The best testimonial I could dream of !

I mailed him earlier today to ask his permission to reproduce his comment on my website (The JoS forum site doesn't mention any copyright on the contents but I'd rather have his agreement). "Sure!" was his reply.

I'm so happy :-)

Conclusion

Feel free to evangilize the world about appTranslator :-)
But please be careful to the backfire I may be victim of ! There might not always be a fireman as efficient as Joel. If you're posting to a forum with a big audience (good idea!), make sure it cannot be mistaken for Astroturfing, because, as Joel told me, there are lots of self-appointed moderators that will be too happy to attack appTranslator (and whether they're right is the least of their concerns).

PS: Don't look for the testimonial on apptranslator.com right now. I'm going to change the contents of the home page soon. It wil appear then. Edited on May 24: Joel's words are now in good place ;-)
