In addition to reading weblogs, as some comments have suggested, you should consider starting your own blog.. If you are discreet about it, you could place the occasional link to your writings in other places. At some point your audience will select your writings and can become the correspondents you desire.

Addition: Tim Porter suggested what I think is an excellent theme for your new blog, 'Mathematics In Retirement'. He didn't tell me where he got the idea though. End Addition.
