I suppose it depends on why you do the blog. To evaluate its worth, think about its purpose and intended audience. Is it a recruitment tool for vocations or a way to communicate news and events at your community or both or neither? You might not always get feedback from others about it so you need to feel good about what you are doing for its own sake - is it worth your time and effort to you? How are you judging its effectiveness and value? Relying on others to validate your efforts might not always work on the Internet - I know I watch a lot of YouTube videos that I like but I don’t stop every time to click the like button. It’s probably the same with your blog, people who read it and like it just might not be bothered to say anything.
I have noticed one thing about people - they tend to complain more than they praise. If you look at reviews of anything online, the people who have something bad to say about something (a product or service etc) are more likely to go to the trouble of posting than those who have something nice to say. That’s why I take all online reviews with a grain of salt.
Are you still enjoying writing your blog? If so, then keep at it, and just assume that there are people out there who are enjoying it along with you. If it has become a burden to you because of your other responsibilities and time constraints, then post less often or not at all - it really depends on what works for you.
Personally, I enjoy your blog.
