Well, the IB staff do like to imply the software is popular, so I thought I'd have a little fun with them and see how many vBulletin 5 sites I could find scattered across the internet. And so, seperated by things like version and whether they're using vBulletin Cloud, here are the 'huge' amount of sites running Internet Brands' 'flagship' software! vBulletin Cloud Morally Bankrupt - A Test forum by SneakyDave used to test vBulletin Cloud's 'features'. http://morallybankrupt.vbulletin.net/ Shade Tree Muscle - One of about three legitimate vB Cloud customer sites, it's about cars apparently... http://shadetreemuscle.vbulletin.net/ Cyber Police - vB staff member BirdOfPrey's hilarious 'test' forum. http://cyberpolice.vbulletin.net/ Mudslide - vB staff member Lynne's test forum. http://mudslide.vbulletin.net/ Scrotnig - vB staff member Mark B's test forum. http://scrotnig.vbulletin.net/ From Sole to Soul - A very dead paranormal forum. Appropriate really. http://www.fromsoletosoul.com/ West Coast Firearms - A gun forum with no actual pages or sections, let alone content. http://www.westcoastfirearms.net/ Not vB Cloud All India Forum - An indian message board with very little activity. http://allindiaforum.com/ Mini Cooper Register - A forum about mini cooper brand cars. http://forum.minicooper.org/ Letting Agents Forum - A fairly inactive property forum http://www.lettingagentsforum.co.uk/ Cant A Fly - A fishing club's completely empty forum. http://www.cantafly.com/forum The Lupus Site - An actually quite popular forum using vBulletin 5, with a decently modified style. http://www.thelupussite.com/forum/ Stairlift Forum - No guesses what this is about. http://stairlift-forum.co.uk/ Globo Forum - I think this is a test forum. http://www.globoforum.com/ What Mobile - Another active forum, this time about mobile phones. http://forum.whatmobile.net/ The Wrestling Game - No idea what's up with their forum set up, it redirects to a single topic. http://forum.thewrestlinggame.com/ Rolex Vintage Forum - Watch discussions, the very dead version. http://rolexvintageforum.com/ AAT - They switched to vBulletin 5 recently, they presumably suffered a loss in activity. http://forums.aat.org.uk/ Used to Use vBulletin 5 Planet Minecraft - Now uses phpBB. http://www.planetminecraft.com/forums/ There are others, but I think that sums up vBulletin 5's 'popularity' quite well. Indeed, how about a few figures? Out of all the sites I found, exactly TWO (minus the official vB support forums) were brimming with activity, namely the Lupus Site and What Mobile. Practically no one uses the latest version (vBulletin 5.0.6) outside of the vB Cloud, indicating that no one really cares for the vB 5 upgrades. At least half of all sites had no content whatsoever, and around 95% were completely dead. This indicates either that vB 5 is only selling to complete amateurs (probable), that your average forum goer doesn't care for the software and want to join sites using it (also probable) or that the software just isn't fun to use/maintain. 14 out of about 20 sites had only changed a few colours/the logo, implying that forum styling with the script is neither easy nor pleasant. Exactly 63 modifications for the software exist on vBulletin.org. This is about 38 times less than there were for vBulletin 4, and 131 times less than for vBulletin 3. The total numbers for each main family's mods are: vBulletin 3 - 8312 modifications vBulletin 4- 2441 modifications vBulletin 5- 63 modifications So the software has literally lost about 3/4 of its popularity between vBulletin 3 and vBulletin 4 and then even more between vB 4 and vB 5. How much? Apparently, vBulletin 5 is just 3% as popular as vBulletin 4. And so there are some stats for the curious, in case you want to see both the quality of the sites using vBulletin 5 and vBulletin's general popularity in recent years.
