I am in the process of transferring my webcomic Actual Stuff (NSFW) from ComicGenesis to Tumblr. I’m still in the process of getting my archives transferred over (and I’m taking my time about it so it’ll be a while before the whole comic is moved) so I’ll be putting new updates on both sites for a while still. Eventually I plan to have all the archives moved and be using the Tumblr exclusively, so be sure to update your bookmarks.
Not that ComicGenesis hasn’t been good to me over the years, but it’s just become too outdated for what I need.
And in a few years when Tumblr has become outdated I’m sure I’ll be moving it again to SocialAgro.org or whatever is popular in the future.
