Could be several things. So first; where's the hole? Is it on the inside, next to the rim, at the edge, are there two holes about an inch apart (snake-bite puncture) or is it definitely something coming through the tyre?

If it's an actual puncture then use better tyres; I'd recommend Schwalbe but there are many good makes that other riders swear by.

If the tires are inflated properly than you need beter tires. I recomend http://schwalbetires.com/marathon_plus_page
I replaced my rear tire after about 15000kms (all over Europe, all tipes of roads) without a flat.
cheers

schwalbe marathons are touring tyres..

go for Hutchinson python! they're comparetively cheaper than those touring ones, quite light and really puncture proof

And I don't know how is it possible to get flats so often, this year I toured all Scandinavia with a cheap shit tyres, something like xiang-wang or somthing and I didn't get any flats at all plus the bike was absolutely fully loaded and I did some really really harsh gravel washboards so.... the point is you need to put them up properly

cheers

Murphy's law.
I have had a penetration puncture on a new touring tyre that was guaranteed against such an event.

I also had this problem. Lat fall I moved to the Dallas area and decided to try and ride to work one or two times a week. I thought I would save some money, this was when gas was $3.20/gal and I figured the exercise would not hurt me any.

In any case, I literally, had 6 flats in a matter 6 weeks. That is almost every time I rode. I either did not make it due to a flat or I had a flat by that evening and could not ride home.

The tires are 26"x2" Hybrid tires. I changed tires with another bike I had, I changed rims with the same bike. I bought a tube with the goop in it that is supposed to stop small leaks... I took it to the local bike shop and they could not find anything. Yet I got another after my next ride.

To make this long story shorter, the problem turned out to be I was under inflating the tires. I am 200+ lbs and I was inflating to 45 lbs which, apparently, could not support my weight and the bumps. and if I hit a bump in the roadway I was crimping the tube. I now keep the tires at around 60-65 lbs and I have not had an issue since.

i have slime (http://www.slime.com/tiresealant/index.php) in my tyres as well as that they are schawlbe. before that i got about three flats in a few weeks (o.k so the third one was the repair undoing itself) , s**t happens.
