A comment for those seeking to use this site for personal gain: Given the increase in requests, let me be clear. I write on this blog because I want to. It’s my hobby, my playground. Sometimes people point me to interesting products/services and I write about them. But any request regarding ads or sponsored placements ends up the trash without a reply. And if you think something would be of interest, differentiate yourself from the spammers by referring to a posting — in an intelligent way. (I get enough auto-generated mails to identify them immediately.)
BTW, posts can get updated after I published them if I spot spelling errors (not a native speaker) or think a different wording might improve precision and clarity.
