I plan on using both. Unfortunately, I use a smalls subreddit a lot, and I'm not sure if enough people will move over to lemmy. Based on the poll on the subreddit it looks like it's going to permanently go dark also.
It's both great and not so great at the same time. If the site were easier to navigate with less sluggishness I would have no problem.
I absolutely love the community so far and it has been a breath of fresh air to get away from the toxicity of Reddit.
However, the communities I'm interested in are just not active enough here yet.
I switched to Mastodon almost all at once, but I still check it for, like, five people. I feel comfortable with that. Reddit is much less of a "check it" style thing (it's more of a browsing / doing an activity kind of thing IMO), so I'm not actually quite sure that I'll even end up wanting/needing to go to Reddit
… other than the huge number of [really helpful] Reddit posts that appear in search results.
Personally, I'm not finding Lemmy/Kbin to be difficult and I still plan to use both until old.reddit finally goes away. It's a transition, not a switch being thrown.
But it feels like kissing the girl who cheated on you with two other guys in an ass to mouth threesome.
That's what I am doing. Just a lurker on reddit, comment and post only on Lemmy
