Personally, it's not a priority. Twitter is more fleeting thoughts for me. It's not a timeline of family events & childrens photos like Facebook. So I would never bother to upload my Twitter stream even if I could. I may be in the minority but I'd rather just start over better.
Good to know! I’m with you on starting fresh with my timeline. I *think* I will build out a way to upload your twitter archive for those who wish to carry over, but still researching feasibility
