My main distro is Slackware on my desktop which is also my server and i have Debian Wheezy on my old Dell Inspiron laptop.

For many years i experienced other distros too , had a lot of fun with the BSDs too.

Of course i keep Puppy Linux handy and Gparted too, just in case.

Also installed Ubuntus and other distros on friend's machines!


Busby.

Zero was my vote, although I did try lots of different distros the first five or six years that I used Linux. After a while, I decided to stick with Arch and have been using it solely since 2004.

Was not 100% sure how to answer this

At home I use 1 distro and at work I am on another, so I selected 0 since I have not 'tried' and other distro in many years. But after I voted I read the responses so I guess zero is the one for me

I go on a binge every 5 years it seems , so i averaged it out to 3 , but actually it could be 4 if you add my resource tools .
also Ubuntu 12.4.2 accidentally became 14.4 some how .
my windows XP is still running on 2 of ten comps.
Past favs include PC linux 64 bit back when XP was not . Red Hat before they started charging a yearly fee [ which was higher then windoze ! ]
ubuntu finally worked in 2012 and have settled in . ,
I still need to learn more to get a smaller version to work on all my old 98SE systems . or more money to buy a new system ] lol

Though I use different distros for different tasks I have voted Zero, since I don't actually try different distros. I am well aware which focus and capabilities the different distros have and choose based on that knowledge which distro to use for which tasks. I very rarely choose something different than the "base distros", like Debian, Arch, Gentoo and Slackware (I just don't like RPM, so no Fedora/RHEL), I mostly don't see the point in their derivatives (with the exception of Salix and maybe Ubuntu and Mint).

3-5 is about right for me. Running 5.7 at the moment. Using the Windows exe version on my main hard drive. I keep a spare HD in my computer (disabled in BIOS) for whenever I see a new distro I want to try. Keeps me out of trouble.

2: Slackware 14.1 and Slackware Current Not much else is interesting .
Devuan will get some HDD space, veteran admiration. Maybe a glance at released Debian Jessie Live, morbid curiosity.

Every couple of years I try an updated Ubuntu although one of my laptops is now so old I can install it without doing something or other mysterious to memory management. Ultimately I continue to use Windows because I absolutely have to use QuickBooks. I could learn to live with the inadequacies of LibreOffice but there is no way around the need for QuickBooks.

I recently retired. I am totally self taught with computers. I don't plan on retiring from that.

I have tried over a dozen Linux OSs in the last couple of weeks. Spring is coming, though, so I won't keep that up for the whole year, but Linux is a great hobby for retirement.

Totally agree...... it keeps the old grey matter ticking over.

Like most people in my early years with Linux, I used to distro hop, then after using RedHat, Slackware & Debian, I stayed with Debian based distros, right up to the time I found AntiX, which is my main distro.

I will occasionally try others such as *BSD, Minix, Haiku, etc, so I put in '2'.

Ever since I ventured away from RedHat and Fedora to try other distros, I'm up to about 3-4 per year! My list so far: Fedora, Ubuntu, Kbuntu, Lbuntu, Mint, OpenSUSE, and LXLE.

I'm using Ubuntu 14.04 LTS currently and so far, so good.

Personal systems (desktop/laptop/workstation):
*Debian
*Slackware

Others:
*Fedora (new stuff)
*Raspbian (Pi)
*ChromeOS (netbook)
*Arch/Gentoo (Arduino)
*RHEL/CentOS (work related)
*Android (phone)
*Stephenson's Rocket /SteamOS (gaming)

... meaning zero new ones for a full year (probably for the first time ever).

According to this DistroWatch antiX 15-beta1 package list, there's no systemd, that's very interesting since antiX supposedly follows Debian testing. I just might have to give it a try.

...

I've stuck with Slackware and LFS as well as FreeBSD, so for me, I try zero.
