Ask HN: How do you keep track of blog posts you keep meaning to write, but don't?

Keeping track of something that hasn't yet happened (at least in terms of blogging) sounds a little frivolous. Maybe you just don't have anything to say? Try approaching it as PG does, post an extrapolated anecdote. (aka an essay, see: http://news.ycombinator.com/item?id=369141) Otherwise start from square one, pick up a good book on the writing process and don't even worry about blogging, and instead focus on writing as a craft in it's own.

I use MarsEdit (http://www.red-sweater.com/marsedit/), though I'm probably not a good reference as I haven't updated my blog in awhile and I have over 20 draft blog posts (some have been sitting around for more than 10 months).

I write them as email drafts, since I know its the only thing I'll usually always have access to.

I struggled with this too and I still don't have a proper solution. Text Docs for very early stage idea, Wordpress Drafts/Private Posts (in older version it would put them at the top of the page).

I've tried lots of ways (Excel, text docs, google docs) but I settled on using OneNote for it today.

in what context? personal blogs or professional/company?

i stopped personally blogging since i didn't have enough consistent ideas or drive to write instead of other stuff. with a company blog, i'd use something shared, maybe something in dropbox.
