This seems like it’s a difficult thing for some, so here are some tips:
1. Follow a few blogs that reblog or promote other blogs:
~-~* simblrdirect.tumblr.com/S3D - directory of various creator simblrs for TS3
~-~* http://pis3story.tumblr.com - directory of story simblrs for TS3
~-~* sims3tutorialhub.tumblr.com - directory of tutorials for TS3
~-~* http://sssvitlans.tumblr.com/tagged/s3cc - still the most organized archive of TS3CC I’ve found, even if perhaps not quite as active for TS3 as for TS4. Searching her archive is a great way to find TS3 creators, past and present.
~-~* sims3decor.tumblr.com - sporadic reblogs of TS3CC
~-~* http://ninthcirclets3cc.tumblr.com/archive - gothic/dark/lolita etc. TS3CC
~-~* http://scifits3ccblog.tumblr.com/archive - SciFi/Dystopian etc. TS3CC
~-~* http://fancifults3cc.tumblr.com/archive - Fantasy/Historical TS3CC
~-~* http://ktccfinds.tumblr.com - my personal cc side blog
That’s most of the TS3 finds/directory blogs I follow... because I mostly just follow the individual creators these days, but these blogs help me find new creators. Non-creators I mostly find via other blogs I follow - see below.
2. When you download something from a creator off of a CC finds blog... FOLLOW THE CREATOR!
CC finds blogs don’t always re-blog every creation a particular creator releases, and even when they do, it’ll always be slower than simply following the creator themselves.
So go follow your creators, leave some likes on their original posts. It encourages them to continue creating!
3. Do a tumblr search for the following tags:
Protip: Try different spacings of words in tags or different spellings, ie: ‘#sims 3 #thesims3 #the sims 3′, etc.
4. When a blog you follow posts a WCIF, follow the link...
...even if you’re not interested in that particular item of CC.
I’ve found SO many blogs this way... some active and some not.
5. Take a peek at the notes of posts you particularly like...
...to see who else is leaving likes or comments on their posts.
It’s an excellent way to find fellow simblrs that may have similar tastes to yours.
6. If you find a blog you like that seems inactive... follow it anyways!
I’ve done this a lot and am always delighted when some of those blogs become active again after a while. I’ve gotten to know some awesome simmers this way.
7. Pay attention to the tags on the Simblrs you follow.
Try searching for other blogs that use those same tags. (See step 3.)
