After reading a thread or two here in February I left on March 1 on a 10 week RV excursion committed to greater use of my 18-150 M. At the end I had taken 916 photos (after deleting some duplicates). After deleting some redundant photos and merging some panoramas (mostly taken with the 18-150 set at 18mm) I had about 450 photos that went on-line.
With all due respect, but why do you put 450 photos online? Who will watch it? Before sending this message I looked at your website and I need to write there are nice pictures. Congratulations! But in your website are only 100 photos from the period of 3-4 years. And now suddenly 430 within 10 weeks. Is not it the junk production? I know it's only 6.5 pictures a day and it's not so much. But for God, there are millions of pictures on the internet, who will see it all?
A very good question. I have about 60 friends (mostly from many years past ... I'm 77 now) that follow my photos. I do a bulk emailing after each posting. Many of these folks are approaching retirement and planning their own trips in the Western US. They seem to appreciate the photos from the responses I get. Some are older now and cannot travel so re-live their visits to interesting places via my photos or just enjoy seeing things they were unable to see when they were younger (one fellow is in late 90's and is always the first to express appreciation).
Also, I recommend only the first album to these friends. It contains 90 photos with several covering each stop on the 10 week excursion. I'd say most of my friends stop with just that album. I suggest they go to one of the 30 odd specific albums only if their interested is piqued by the corresponding photos in the overview album.
Also, I don't leave all photos on slickpic.com. When I have time I'll thin them further for whatever benefit others may find. Many will be moved to other existing albums and replace existing photos if they are an improvement from my earlier days. Some places we visit often such as the California coast or Yosemite or Death Valley and I often get better shots now than 5 or 10 years ago. Some of the 30 or so albums will disappear unless they are noteworthy and all will be reduced in size, some to 5 or 10 photos.
I'm not sure how you determined the count, but there are 2250 photos posted with 450 new ones this year. The albums go back about 15 years with most from the last 10 years. So roughly 1800 photos from 15 years or about 120 per year on average. Probably 1900 total after I thin down the recent postings.
Then there's the problem of tossing perfectly good photos. That's hard to do. About once per year I go through my collection in Lightroom (about 4000 photos currently) and delete some to keep the number under control. Often I am deleting one that is posted (LR tells me this when I try to delete) so some end their time that way. If a photo is not posted I'm very likely to delete it.
I have hundreds of thousands of page views and hundreds of likes and a good number of followers. So there must be some interest.
Some amateur photographers use sites like Slickpic.com to backup their photos. I only post not very large jpegs so I'm not backing up, just putting them out there for others to enjoy or download or explore possible destinations. Just as I use other's on-line photos to choose destinations for my RV trips. I also learn about good vantage points from photos I find on-line.
I've made a number of friends from the comments I've received and converse often with one fellow that has interest in destinations much like mine. He has guided me on a number of excursions into Wyoming, Montana, Utah, etc.
As for who will see the many photos on the web. I know I won't. I spend more time shooting than perusing. But, as noted above, I do spend some time studying possible destinations, and though I surely see less than 1 in 1000 photos photos for each one, what I do find is helpful. Heck, I've learned a lot by looking at other's photos and tried take my own versions of quality ones.
PS: I just noticed that there are about 300 photos from 2018. Clearly I am behind in my thinning. I'll thin 2018 soon.
PS: Also, as you likely observed, Slickpic presents an album 2 or 3 images across. Large thumbnails if you will. It's easy for a viewer to skim down through dozens of images every couple of seconds and click on none or click on just a few to see full screen.
). I will upload some night pics I have shoot with this lens in the thread 
Well composed. I prefer the second and fourth. Congratulations!
