I have between 60 and 70 domains. Some are in use, some are premium (at least to me) and I've held on to them for several years now.
116 with 8 more incoming sometime today. 5 in use with actual content,, the rest just waiting for some response as to who is the best domain park. Right around 100 of them are all the same topic,, wanting to launch a network of sites all linked to one another with adsense on them... wow , that was a mouth full... it will either make me a lot of cash or drive me crazy trying..lol no way do i want 1k domain names like webmistress... kudos to you,,,, My hair greyed just thinking about that..lol
well rite now only 10 domains. out which 5 are active and 3 in pipeline and 2 redirects. And make buy around 10 more as redirects and future projects.
