You don't need to have fans or admirers to 'get somewhere digitally'. Many of the most successful writers online are found and read purely through search engines and keywords. Having fans and followers is 'nice' in terms of getting feedback and praise, but it is not essential. I don't see any reason to have a limit on followers either, as some people seriously do want to read your stuff, and the easiest way is for them to be notified when you publish. Do bear in mind that most 'followers' do not actually read your articles though, and if you are lucky maybe 5% do, and the rest followed you on a whim, because you followed them or because they want you to follow them back.
